Burning write protected DVDs

i feel like such a n00b but what the hell....what programs do you guys use to copy write-protected dvds??

DVD Decrypter, then dvd shrink to get it to fit on a 4.7gb disk. Although I only put the movie on the disk and none of the extras. But I only make copies so I can have legal backups if my disks get scratched. :)

DVDFab Decrypter is better.  And legal!
