Comment (by Phil <pmagnone@…>):

 I'm doing a lossless transcode of an MPEG-2 TV recording (720P w/ AC-3
 audio) just to snip the commercial breaks, at which point I usually use
 Handbrake if I want to archive the video with better compression.  I've
 tried transcoding multiple shows from multiple channels, but I still get
 the same result.  Each time it stalls at 80-90% and "mythtranscode" shows
 ~100% CPU usage in "top", and I have to kill the process manually.

 Here's a 60 second, 99MB clip from near the end of one of those recordings
 (used "ffmpeg -vcodec copy -acodec copy -ss 00:31:45 -t 60 -i [input].mpg
 [output].mpg").

 http://dl.dropbox.com/u/162975/test.mpg

 While navigating my recordings directory, I noticed that there was a
 *.mpg.tmp file for at least some of the shows I tried to transcode.  Near
 as I can tell, the transcode jobs actually finished (the files play back
 without any issue), but the mythtranscode process never exited correctly.
