This is probably a very bad idea because of telecine and field-coded

No, -ss just fails on NTSC DVD's because the idiotic telecine junk
makes it seek way too far.

Because avi files >4gb (or is it 2gb?) can't have an index.

Anyway, the correct way to do what you want is:

  mplayer -dvd 1 -dumpstream

This will dump the whole DVD to a file named stream.dump. Be sure your
filesystem, kernel, and libc can handle files >2gb tho! If not you
might want to dump chapters separately or use the vobcopy program to
copy the DVD to your hard drive instead.

Also remember to use -ofps (if necessary) when you go to encode it
later, just like you would if it were a dvd.
