Meanwhile, OUTSIDE the USA...
Well I do, and my DVB-T devices are all based on MPEG2, as are all of the digital broadcast signals here in the UK. If DVB-T starts broadcasting MPEG4 then a lot of devices are going to break, which in turn would mean that there would have to be a lot of advance warning given. And I'm not seeing any right now.

Well obviously we all want accelerated MPEG4 / H.264 / VC-1 but that doesn't mean that I wouldn't want to accelerate MPEG2 either! I don't care if my CPUs are "up to the task" of MPEG2 - I might be using them for something else at the same time!
My point was that I'm not seeing a lot of demand for accelerated MPEG2 playback - the bulk of the interest is in MPEG4, which XvMC does not directly support.
Are you asking about MPEG2 (XvMC) or MPEG4 / H.264 / VC-1 ? They really are two different questions.
Are we just talking about just R500+ here? I do have older machines with CPUs barely capable of MPEG2: R100, for example. (Or possibly rv100 - it's a Radeon 7000.)
I also happen to be a C developer with time on my hands (apart from WoW, which is like a black hole for free time) so what's the harm in a little extra functionality?
