Interesting. I tried using the cutpoints from previous runs where
things worked, and it runs to completion again. Looks like where
the cutpoints are affects this. My two command lines...

Working:
nice -10 ./mpeg2fix -i /data/mythtv/1014_20051017222900.mpg -o test2.mpg -c "0 - 7960" -c "40761 - 48204" -c "70560 - 78037" -c "141288 - 148735" -c "189744 - 203159"

Loops:
nice -10 ./mpeg2fix -i /data/mythtv/1014_20051017222900.mpg -o test.mpg -c "0 - 7960" -c "40750 - 48204" -c "70560 - 78037" -c "141288 - 148735" -c "189744 - 203159"

It looks like that first cutpoint change (from 40761 to 40750) is what does
it.

Output when it stops
Failed to decode frame.  Position was: 0
mpeg2fix: mpeg2fix.cpp:788: bool MPEG2fixup::process_video(MPEG2frame*, int): Assertion `state != STATE_BUFFER' failed.
Aborted

I'll send the rest of the logs direct as they are two big for the list.
