The mpeg2trans stuff worked for the tests I did before committing the 
patches.  It'll honor the cutlist without re encoding and produce a file 
that doesn't suffer from a/v sync issues.  The video stream is DVD 
compliant but the audio stream is still MP2 (AFAIK) which means some 
work needs to be done for it to truly be DVD compliant file.
