I don't know of any way to fix that particular problem. (It may be possible by 
adjusting settings in mencoder and doing the transcode directly via an 
mencoder command line, but mencoder is a bear to use manually -- check its 
man page to see why!) In the future, I suggest NOT transcoding recordings in 
MythTV if you plan to burn them to DVD; the fewer transcoding operations, the 
less chance there is for errors to appear, whether like this or something 
completely different. FWIW, I've never encountered this particular problem in 
files I've recorded on my MPEG-2 encoder cards, even after transcoding once 
via my script (and hence mencoder). I have seen a similar problem on files 
I've downloaded off the Internet, though. (YouTube videos are often like 
that, at least as played with mplayer.)
