Good.  I think you may have fixed a primordial bug here.  I edited the 
patch into my current version and a test run with a multi-segment 
high-ratio cutlist successfully created a DVD image with the 
MythCenter-Animated theme and auto-created equi-spaced chapter markers.

Then I masochistically tried combining the cutlist with user-specified 
chapter marks.  This is perhaps a bit exotic but I couldn't get the 
marks to stick.  My normal practice of applying the cutlist before 
entering MythArchive lets me do it on the rare occasions when it seems 
worthwhile; it also makes it easier to predict the size of the final 
.iso image.

You said earlier that you hadn't updated your version of ProjectX 
because you would have to rework your earlier patch.  I don't think 
that's true.  Newer versions support appendPidToFileName, but if you 
don't need it and don't specify it I would expect them to be OK; 
however, in that case the newer version may not give any benefit.

Cheers,
