When you ran it through ProjectX, what was your output format? I've
used it more than the internal cutter and haven't noticed the problem
you ran into. I output to m2p, but I've been told by one of the
developers that some of the other output modes are still buggy.

Now I need to figure out a good process to use Geoffrey's work outside
of Myth, I basically need a nice graphical way to create the cut list
outside of MythTV...
