Bridgman doesn't care about video decoding, so it is at the very bottom of
the ATI list. :-( Grarpamp mentioned OTA ATSC which is mpeg2, so XvMC is
useful. (And also what I'm looking for.) Supposedly VIA extended XvMC
so that it is useful for other codecs. But I haven't found info about
which boards openchrome supports, and what features really work.

Sorry, the "hasn't been documented and FLOSS code hasn't been implemented yet."
referred to ATI's UVD/UVD2. And my info on VIA is minimal.

Excellent!

Grarpamp might be talking about something like this:

So far I haven't seen one of these articles explain what happens
"under the hood".
