I've tried a variety of versions of mpeg2fix.  0.14 is the first one
that worked for me.  Previous versions shows some corruption (green
blocky flashes) right after the cuts.  0.14 worked perfectly as far as
I can tell, but produced 600k+ lines of output with no debugging
enabled on a 1.5 hour show.  Mostly they messages were:


Found invalid audio PTS (off by 0)
and
Found invalid PTS (off by 0) at frame 0

It's also incredibly slow. To the best of my knowledge there is
nothing wrong with my recordings.  (They're all made with a PVR-250
and a recent ivtv.)  Are these messages indicative of a problem or
just 0.14 being overly verbose?

When I try 0.l5 it's much faster, less verbose but ends with a
reported deadlock.  I'm not at home to check out the recording created
by 0.15 but the file looks to be a tiny bit shorter.  Both 0.14 and
0.15 report the following a number of times:

Warning, QMAT_SHIFT is larger then 21, overflows possible

I'll attach a snippet of the output from 0.14 and the whole run from
0.15.  If you want me to run 0.15 with debug turned on, let me know.
