2 things from me - firstly I wanted to thank you for your (often incredibly) patient and informative contributions to this forum
Secondly... unfortunately I'm still pretty confused! I'm trying to spec up a mythtv box. One major reason for going this way rather than a consumer box is futureproofing - i.e. capability with HD as it becomes more available over the next year or so (Blu-Ray and BBC HD, etc.).
With that in mind, I figure AMD is the way to go - was thinking of something like a X2 5050e. I had been pretty excited to read about the (windows) HD performance of the 780G which also seemed ideal. However I'm trying to work out what level of support is likely any time soon, like over the next few months.
I don't think I much care if that support is open or closed source in the first instance (should I?) Also I don't really understand all this rendering, motion compensation, IDCT, etc. malarkey on a sufficiently practical level to understand the impacts of it all. What I'd like to be able to do is know if and when (approximately) a 780G will be able to decode HD (from Blu-Ray and BBC broadcast) under linux, and which processor it would need in order to do so.
Right now I'm beginning to think maybe Windows is the way forward... please dissuade me as I hoped I'd left it behind! (happy Mac user & linux tinkerer)
Thanks again for all the support, and best wishes with the thrust which it seems to me is pushing you inevitably ahead of "the other GPU guys" in terms of linux support. Which is great, obviously, as it means loads of linux types will end up going for AMD boards and CPUs for both their own tinkering and when building (often inevitably windows) boxes for friends and relatives.
