These are a completely different issue. The one we were talking about is
actually a proper MPEG2 decoder that takes the MPEG2 stream on input nad
outputs video data.
The ATI stuff is a hardware assist mecanism, it's doesn't do the entire
decoding, it does HW IDCT and motion compensation stuff afaik, or that
sort of thing. Anyway, we don't currently have specs on how to use it.
ATI does provide a binary lib for x86 that can be used in linux, I
think, but not for ppc (though I suppose I might be able to get them to
build an unofficial one ... maybe worth asking), but I don't know if we
have players capable of using it.
