DVD to DVD

Response to message from David Miller (see below):

1) In my case the movie is a cartoon, which compresses down really well,
so the .avi file I made was already down to about 2 GB. So I 
abandoned the original plan of making 2 DVDs.
[In answer to the earlier question about "why are you doing this?",
the original dual-layer DVD plays in my computer, but my DVD player 
doesn't handle it for some reason.]

2) I had an extra complication though: I wanted one of the subtitle 
tracks, and the simplest way to get it was to use dvdrip to render
the subtitles directly into the .avi file it produced. That's why
I didn't try to deal with the VOBs directly: they didn't have the
subtitles in them.

3) If your original DVD doesn't have complications with multiple 
sound/subtitle tracks then I think you could just do what you said and 
split the VOBs into two groups and make one DVD from each using 
dvdauthor. Do you know how to use dvdauthor?  I could show you some 
sample scripts to get you started.
