For me vlc plays for 35 sec, mythtv as a recording (overwriting a short
recording made here) or as a video for about 30 sec until the presenter
walks on, then returns to the Watch Recordings screen. If that's where
you see the problem it might be better to have more data after it.
There's a change in aspect ratio just after the yellow countdown, but
that doesn't seem to be a problem. I didn't notice it initially.
You might find the vlc 'Tools > Codec info' informative.
All in MythTV 0.25.3.
