Whew!  Lucky you, you may have missed the super important part!!  ;-)

Nah pretty much that's it:
cat file1.nuv file2.nuv > file.nuv (and I prefer mencoder):
mencoder -ovc copy -oac copy -o file.nuv (to "smooth" it out).

Sweet!  thanks for the heads up!  Another option is to buy the
HD-DVD/Blu-Ray version when they release it so you can spend
yet-another-30-bucks on a movie you once owned on VHS, now own on
regular DVD and want in HD-DVD...

:D
