OK. Thought I would try manually opening the file with avidemux2,
manually cutting the commercials. Did that, then followed the
instructions at
http://www.mythtv.org/docs/mythtv-HOWTO-21.html#ss21.19

I exported the video, exported the audio, then did mplex -f 8 -o 1.mpg
1.m2v 1.mp2 to get the final mpg. Problem's still there when I play
the final mpg file.

Here's my mjpegtools version:
Name        : mjpegtools                   Relocations: (not relocatable)
Version     : 1.6.2                             Vendor: Freshrpms.net
Release     : 4.1.fc3.fr

Seems that the problem must either be avidemux or mjpegtools...
