Step By Step: Building a MythTV PVR for $635 282

hesby writes "Anandtech has just published the first half of a two-part article on building a MythTV PVR that they will ultimately compare with Microsoft's Windows Media Center Edition on very similar hardware. As a result, they selected some components that the average user might not choose, just to keep things fair in the second part, where they pit the two PVRs head to head."

          Only up to 137GB due to long-LBA issues. Only the HiDef Tivo supports LBA48, allowing HDs larger than 137GB to be recognized correctly (it still recognizes larger HDs, but only sees the first 137GB). The most you can get for a regular Tivo is 300 hours of TV.

          For the PC based Tivo, if I get a RAID 5 card and a few 250GB HDs, I could have 1TB+ of storage - enough for TV shows and a video on demand system with a bunch of my DVDs ripped. Yes, it gets a lot more expensive, but 250GB drives are under $150 these days (Fry's ad had both PATA and SATA 250GB drives for under $150 - no MIRs).

I love tv, don't get me wrong. I just have no idea when I would be able to watch 300 or more hours of tv. And, I am assuming that the PVR's are sucking in more each day.

But its far more substantial that just pluging in a new HD.

              The whole DVDs-on-demand is the primary reason why it would be better to use a PC based PVR as opposed to a Tivo. If all you want is more TV, then get a Tivo.

          yeah. but then you need to factor in $20 or $30 for a tivo-compatible USB 802.11b adapter... but the reall killer app for Myth that TiVo just doesn't offer at all is the burn-to-dvd option included in the parent's spec.

          Tivo lets you play stuff back through a VCR or standalone DVD-R, but that's a half-assed solution at best. The integrated TiVo + DVD-R boxes from e.g. Pioneer are over $500 [crutchfield.com] for just the hardware. add $300 for lifetime service, and that MythTV box starts to look downright cheap.

          why would you want to burn to DVD? well, because you might want to archive something on broadcast, or make copies to give to your friends. As a for-example, I'm on a masters' water polo team, and I'm fanatic about watching and playing polo. But there is never any polo on American TV... except during the Olympics! So yes, I went to Circuit City and bought a $99 TiVo with the 40-gig disk for the SOLE PURPOSE of recording olympic water polo matches. But guess what? Everybody on my team wants to watch them too, but since Tivo records the whole 8-hour block of programming, I had to delete some games from Tivo to make room for the next games. And I noticed something interesting- whatever algorithm Tivo uses to compress the video stream, it has some problems with water, especially at the lower quality settings... Often I could see rectangular divisions in the surface of the pool, and it's even worse on the VHS tapes I tried to make from the TiVo.

          When you buy a Tivo, you're buying convenience, but if you also want to buy the ability to make archival copies on DVD, you're going to spend $500 on hardware either way... and then the MythTV box does save you money because you don't have to subscribe to get progam listings.

        Not a bad list, but you really should "splurge" on the Happguage PVR-250 card. It does the encoding in hardware, so even a low end box could easily support two tuners. With the card you put in your list, all the encoding would fall on the CPU. Not only that, I'm not sure that nVidia's personal cinema is supported under Linux. An integrated video card (on the motherboard) would do fine as long as it had TV out that was supported under Linux (and looked half decent). Wouldn't even need that if you used a monitor.
        • Yes, but it doesnt encode directly into the latest Xvid/Ogg/MKv format does it?

          I dont think there's much point in putting such rapidly changing things such as video codecs into hardware, when you can economically buy a fast enough processor with high memory bandwidth, like an athlon64.

            It's MPEG2. That's pretty good. I wouldn't be suprised to see MPEG4 in the next year or two. As for the audio, transcoding that takes no time at all.

            Yes, codecs change fast, but when you can offload 95% of the work the box would be doing, that's nothing to sneeze at.

            Besides, you could record in MPEG2, and use your now free CPU time to do the transcoding (which you can also do when nothing is being recorded). That way you get the instant gratification of having things recorded small (and your CPU could handle 2 or 3 recordings at once as long as the HD could) and you could run a low priority cron job to transcode things when nothing else is going on so you get the space advantage.

            But if you plan to backup (or just copy) onto DVDs (which are MPEG2), then recording in MPEG2 makes even more sense (because you wouldn't need to transcode to make a disc that would play in any player).

            As for the Athlon 64, yes it could handle one or two encodes in real time, but with a RAID and a few cards, you could record 4 or 5 streams with hardware encoding. Also, MythTV supports multiple front/backends. That means you can take your old PII 233, stick a PVR-250 in it, and with a little setup it would look like an extra tuner to your main MythTV box. That would only cost you $99 or the card. Your idea would require a much faster computer.

            The ideal solution would be some very fast ASIC/DSP/PGA that you could configure on the fly to do hardware encoding of any format, but that probably won't show up for years.

            Also note that a hardware encoding chip does the work much more efficently (in terms of electricity used and heat produced) than a general purpose processor like a P4 or Athlon 64.

            It's recommended to have about 1Ghz per encoder, so if you want to record two programs, and be able to watch something, you're going to need at least 3 Ghz. Even with this much power, though, there can still be glitches when viewing or recording due to load. However, with with two Hauppauges you can record two shows and watch something at the same time with the machine hardly ticking over.

            It's not unheard of to have both a Happguage and a different TV tuner card in the box as well, for when you want to record straight to a format other than MPEG.

            Also, many people choose to use a less powerful, but smaller, quieter, and cheap machine like a mini-ITX as a PVR. In this case, it's a requirement to use a Hauppauge if you want to watch and record at the same time.

          I can only echo the advice for using a PVR-250 (actually I suggest the PVR-350, which is encode and decode).

          I've got a MythTV box running on a VIA mini-ITX using the slowest CPU offered, a fanless 533 MHz C3 "Eden." With the PVR-350 it loafs along at sub 5% CPU loading. The only downside to this slow of a CPU is occasionally there's a lag in menu selections or screens that need to do a lot of database work to update, but given the power savings and the fact that the box can be fanless, it's worth it.

          Even cooler, I was able to use MythMusic to rip all my CDs that had been living in a 200 CD changer -- now I've got on screen menu, random access to the collection with complete artist/title info, instead of having to look up that a favorite CD is #153 in the changer. And I can create any playlist I want with minimal effort.

          Tivo doesn't do anything like this -- one more advantage for MythTV.

          Start adding up the cost of consumer electronic devices a Myth box can potentially replace, and it doesn't take long to make a compelling argument based on expense alone.

That's still about $250 under what the box in the article is. For that extra money you could get a 140 hour TiVo and still have $50 to spend on something else.

    Or, if you have DirecTV, you can buy a DirecTiVo for about $100 and monthly service is $5 on top of your DirecTV bill. So that $650 will buy you the lowest end DirecTiVo and 110 months of service (about 9 years). DirecTiVos are wonderful machies, and can record two things at once, and it's all pure digital. I don't know the prices, but for $650 you could probably get a HD-DirecTiVo and a few months of HD/TiVo at least.

    All that said, check out MythTV. If you already have parts on hand, it would be cheaper. It's a fun little project that can do tons of stuff, and there is no DRM (always a /. favorite). It was facinating watching the development list when I did. At that time they were discussing (and testing) ways of automaticaly skipping commercials, and it was very interesting to read. They talked about blank frame detecting (but you have to be careful so you don't miss a Simpsons's "eyeball" scene), using time (commercials come at fairly regular intervals), "bug" detection (the logo in the corner), etc.

    MythTV can also show you weather, they were working on DVD and video playing as I remember, and MP3 playback. Plus you can have different frontend and backend boxes which would allow for very cool things.

    All that said, if you just want a DVR, a TiVo is probably better. If you want your own Home Theater PC that can do all sorts of stuff and you want to be able to extend it yourself, check out MythTV.

    • Your basic point is 100% right on, but an HD TiVo is still about $1,000.
      • After posting I checked on the DirecTV site to see if I could find the price. I could barely find the page, so I figured that might be true.

        But, if you've got the money for a HDTV and want a PVR and could afford the $650 to build one, there is a decent chance that you can afford a HD TiVo instead.

    if you're interested in building your own PVR, you should take a look at EFF's broadcast flag page:

      It's the responsibility of the driver and software to enforce the broadcast flag, not the hardware. There are open source Linux drivers for many DVB cards, so even if the hardware supports the flag, open source drivers are clearly not going to enforce it. Vendors that fail to provide specs or open source drivers will simply have their products reverse engineered anyway. This has happened with many current video encoders (look at the Hauppage PVR-350 series and other DVB devices) and there is virtually nothi

It'll be almost exactly the situation we have with the Xbox. It's simply the only way to sell hardware that complies with the law.

          Fine. How to set up a TiVo:

          1. Take you TiVo out of the box.
          2. Oh and ah, then pet TiVo affectionately.
          3. Put batteries in remote.

          5. Set the channel switch on TiVo to "3".
          6. Connect one end of red/white/yellow wire to TiVo and other end to TV.
          7. Connect one end of phone cord to TiVo and other end to phone jack.
          8. Plug in TiVo, turn it on, and turn on the TV.
          9. Set the TV channel to "3".
          10. Follow the on-screen instructions.
          11. Record stuff.
          12. Watch recorded stuff.
          13. Drink beer. Eat chips.
          See? Easy. No, recompile of the kernel was necessary.

    I can play MAME, pull up local movie schedules, RSS feeds (*cough slashdot*), instant weather (no waiting on the 8's on TWC for me) on my DIY PVR, not so much with those features on the TiVo =)

    I have used all three: Tivo, ReplayTV, and Myth. For my money, I choose ReplayTV hands down. I currently own 2 of them.

    Replay TV is about the same price as a Tivo. And unless I haven't seen the latest version of Tivo yet, you still can't easily get the vids off of your Tivo and onto a PC. With Replay TV, it is easy. Use a piece of software called DVArchive.

    And yes, you can share recordings with other ReplayTV's of the same (or similar) model. Yes, you can program it over the web (my.replaytv.com I think it is, I never use it personally)

    You can buy a good ReplayTV 5040 unit on Ebay for about $300 last I checked. This model has automatic commercial skip, and 30 second skip if you prefer to do it manually. I have one of these models and it kicks the crap out of my cousin's Tivo simply because I can network it with the 10/100 port on the back and get stuff off of it and onto my PC.

    Lastly, if you want a bigger hard drive, there are instructions for installing dual 160 GB drives out there on the internet. I personally have plenty of room on my 40GB drive since I can archive to my PC.

    Tivo I give a 7/10, Myth I give a 6/10 (mostly because it is more tedious to set up and lacks the all around neatness in the entertainment center) and I give ReplayTV 9/10. I do wish they had the thumbs up/down type thing Tivo has.

My box does what I want it to, not what someone else thinks will sell best. If I want three tuners, I can have them. I can have as little or as much storage as I want. I can watch shows from any computer on my network. I can transcode recorded shows into any format. It's all about the freedom to do whatever I am willing to put the effort into.

    If you want to save money, buy a Tivo, it's a good product. If you want convenience, rent a dvr from your cable company. I want more than that, and am willing to spend the time and money to get it.

    I don't know what those reviewers are smoking. Don't get me wrong; I have a Myth box, and I like it a lot. The software itself rocks. But the documentation is a huge haystack of braindumps without a map. These guys put Myth onto a box in a relatively short period of time, modulo distribution problems. That sounds to me like they've read and reread and rereread the docs enough times that they know what's where--they've done it before and don't need a map any longer. For a first time Myth user, the docs are going to blow your brain into little pieces, and it's going to take you a long time just to absorb what's relevant to your system from them unless you have a really standard (i.e. just like the developers') machine.

    Oh, by the way? I have a job already, and a family, and a life. So don't tell me it's my fault I can't digest the haystacks and make a map for the world. I'm a supporter of Myth, I'm just saying that the review does not set reasonable expectations for the effort it takes unless you're installing KnoppMyth.

    - I can watch the recorded shows from any computer in the house from the web interface. The web interface lets me do things like schedule shows, see the program guide, and watch recordings.

    - I can easily burn anything I record to DVD because everything from the PVR-350 is recorded in standard MPEG2 DVD format. I don't even need to re-encode, I just burn straight to DVD (fast).

    - MythTV is way more configurable than TiVo. I mean, there are settings for doing all sorts of things.

    - Things like MythVideo let me watch stuff that wasn't recorded on the machine (like downloaded items or whatever; stuff recorded from your old VHS tapes, etc.)

    And probably other stuff I'm forgetting.

    With the PVR-350 you absolutely do not need a powerful computer. I ran MythTV on a 200 Mhz Celeron system with PVR-350 for over a year. MythTV itself is kinda slow but there are a lot of people working on making it better. The video quality is excellent though. Even the "low quality" (1GB per hour) is way better than what TiVo encodes.
