I tried using your script and it complained about not knowing what 
mencoder or midentify was.  I tried "apt-get install mencoder 
midentify", but it has no idea what midentify is.  My recording isn't an 
HD recording either.  If I understand you right, and mytharchive does 
its own transcoding, then the recording that I have should be OK as it 
stands, however, I still get that error about the frame rates being 
off.  So I'm still confused about that error and the process that 
mytharchive uses to put the recording to a DVD.

Any ideas?
