 An FFMPEG bug occasionally causes the MP2 audio codec to be mis-detected
 for recordings created by pvr-x50 encoders. The problem exists for trunk
 and fixes. This results in several issues for users:

  * no audio on playback

  * preview thumbnails missing since libavformat can not process video
 correctly

  * backend slow/hung due to preview generation stuck in loop

 And the backend hanging causes:

  * playback failing and resulting in "Video buffering failed too many
 times" since the backend isn't responding

  * frontends losing connection to backend since requests to the backend
 timeout

 I've detailed the problem and provided a patch to the FFMPEG project:

 http://roundup.ffmpeg.org/roundup/ffmpeg/issue1149

 Hopefully it will get fixed upstream in time for the next ffmpeg re-sync.

 I'm also attaching a patch for mythtv to this ticket.
