DVD Shrink is utter turd, only use it if you don't give a crap about how bad they will look and how glitchy the DVD will be.
What you really want is DVDRebuilder. Not only is it the best quality (but a tad slower), but you can do batch processing, so it works out much, much faster than any other alternative and you don't have to sit there spoon feeding it.
Just copy your DVDrs to your hard drive, point the program to the correct VIDEO_TS directory, then an output, save that, repeat until you have it done for all, then go>file batch, add all your saved projects, and then it will process them all.
You will get the best re-encoding quality available. If you want just one at a time, but speed, DVD copy 2 is the fastest by far.
Only downside to DVDrebuilder is you need to do a couple of setup steps once, since it uses CCE (and hence why it pisses all over everything in terms of quality). Go to
http://www.doom9.org for the quick setup guide, and the program itself is found in the doom9.org forums.
DVDshrink -> avoid like the plague, the only good thing about it is you can strip crap out, but it really does look like the inside of an ass in the end.
