On Windows, DVDFab HD Decrypter [dvdfab.com] does a great job of ripping. Then use your favorite DVD burning software.
In a nutshell, this is how I do things:
1) Rent from Netflix, 2 at a time unlimited (all issues of throttling aside)
2) Rip discs as they arrive with DVDFab HD Decrypter
3) Compress with DVDShrink (I still have a single-layer burner and besides, the disks are cheaper - I just don't copy the extras or the French audio track, etc., so as to minimize compression of the main movie. This also strips off the ghey previews and FBI warnings. Snatch!) I have used both DVD-R and DVD+R; personal preference is DVD+R. YMMV.
4) Burn result with Nero. Keep files on harddrive for awhile until I'm sure the burnt disk is ok.
5) Whisk Netflix movies back next day. Watch burnt movie at my leisure. ~~
