An anonymous reader writes: It's not only the NVIDIA Linux driver that has been publicly slammed over lacking support but the AMD Catalyst driver is now facing scrutiny from the XBMC media and entertainment software. The developers behind XBMC aren't happy with AMD due to not properly supporting video acceleration under Linux. The AMD Linux driver is even lacking support for MPEG2 video acceleration and newer levels of H.264. AMD reportedly has the support coded, but they're refusing to turn it on in their public Linux driver. Developers are questioning whether AMD even cares about their Linux customers, when the missing features will arrive, and if it's worth the wait.
