I could easily generate a perfectly valid H264 encode at common rates that wouldn't playback on any current cpu in software and vdpau would barf on too. I had something much like that recently for a customer who wanted 1080p at 4Mb/s but they couldn't find anything fast enough to play the resulting files, looked ok for 4Mb/s but certainly nothing near even bad bluray quality.

I've been away until just recently but hoping to get some time to get to the bottom of it in the next week or so, currently regretting the upgrade to 0.24, I wouldn't mind the nagging audio problems back now!

I can't comment on software decode, but clearly vdpau/mythtv can handle
BBC HD because it works for me. What problems do you see? Have you tried
minimyth?
