I doubt that all these steps were necessary, but I took your clip and used
tsMuxer to demux to a .264 and a .ac3 file. Then I used some stuff I learned
from Henk in the following two commands to convert to a DVD-sized mpeg-2.
The video capture seems pretty clean, and I think that's what makes the
conversion successful.

1. MP4Box -tmp tempdirectory -add /path/to/yourfile.264 -fps 59.94
cleaned.mp4

2. mencoder cleaned.mp4 -oac copy -audiofile /path/to/yourfile.ac3 -ovc lavc
-lavcopts
