[mythtv] H.264 over MPEG-2 TS recording and playback

[Mark Buechler]

Looks like newer Myth versions are getting closer to playing h.264 content.
This an excerpt from mfe. I believe the video PIDs are correctly being
identified but ffmpeg is having trouble decoding the stream. The same sort
of errors come out of mplayer (which uses ffmpeg for h.264) as well.
