All versions since I added the PTS wrap code have had assorted issues.
 I'm working on it, but I don't expect many recordings to go through
ok at this point.  The message you are seeing in 0.14 was fixed in
0.15, but the frame insertion logic got broken several versions ago,
and I'm still trying to work out the corner cases.
I checked in some more fixes into svn which should help, though I'm
still not convinced it is right.

The mpeg2fix version is here:
http://www.pblue.org/myth/mpeg2fix-0.16.tgz

This may be the last version of mpeg2fix I release.  I'm going to
include the relevant makefile and build instructions in myth's svn, so
I can keep the code all in one place.  You'll be able tocheck out
mythtranscode, and build mpeg2fix independantly from myth using the
alternate makefile

Note. the debug switch is now a flag, instead of a level.  To get
debug enabled, use '-d 65535'
