Try this:

DVD2OneX <http://versiontracker.com/dyn/moreinfo/macosx/19238>
[versiontracker.com] to compress the dual-layer DVD's down to single layer size. You can get rid of extra audio tracks, chapters/extras you don't want,
etc.

Someone suggested it to me for this purpose. I haven't had a chance to look
at it yet. Perhaps you can report if it does what you need.

Works fine for me. Be aware that it is shareware, not freeware for that program.
