well since we have consumer rights to "backup" our paid for content i dont see anything wrong with ripping a copy to your harddrive. i do it all the time. what works best for me is a nifty little program called Any DVD, this automatically removes DRM from any dvd, or cd that you have in your drive. then i select the proper .vob files from the dvd and run them through divx converter. and voila. i have a perfectly good dvd quality movie ready to be played. the good thing about using divx is that it compresses the movie down to around a gig. and alot of new dvd players support divx so you can burn 8 movies in divx format to a single dual layer dvd ready to be played.
