I use Handbrake too, but only after I've extracted the DVD to disk using another program (DVDshrink). I found Handbrake was unable to handle the encryption on some disks. Then I use Handbrake's "Universal" preset on the extracted files, and it comes out around 2GB per movie. If you watch a lot of foreign films, as I do, the soundtrack & subtitle options are also very handy, though it helps to test them before doing the whole movie. The resulting file works great with VLC Player, and would also work on an iPad if I had one.
