Yes, my MPlayer (and hence ffmpeg/libavcodec) are SVN versions from within the last week or two.

I use ffmpeg and libavcodec interchangably; it's quite possibly MythTV only uses the libavcodec sub-directory of ffmpeg. And no, MythTVs versions are quite old as I explained.

c. Sure not many ppl get the pure TS from sat providers, but I am on the cutting-edge. This has such technical merit that it has to take off and so apps should be able to accommodate.
I don't doubt there are extra nuances to handling Dish streams. However, I'm sorry to say this is outside the realm of VDPAU; VDPAU deals with the PES stream after it's been extracted from the container. VDPAU should handle compliant H.264 streams. Either the dish PES stream is H.264 compliant or it isn't.
