The best ripper I've used so far is DVDShrink. It allows ripping out menus as well as replacing menus with still images to conserve space as well as on-the-fly transcoding. I rip and reburn all my movies as I HATE having to go through that menu crap. I just want to watch a movie. To burn, I use DVD Decrypter. FWIW, the vast majority of movies will easily fit on a 4.7 disc without transcoding at all.
