Hi, I used to use Dvd Decrypter to decrypt my dvds, since they no longer update this program I'm just wondering what everyone else is using? I also use dvd shrink which has a built in decryption but it cant deal with some new dvds I have

What is a DVD Decrypter? I don't believe I've ever heard of one before. What does it do?

You can try DvdFab Decrypter. Do a search for it.

Have a look here & look for videohelp & dvdguides links at the bottom of the 1st post here: CODECs list and alternate players for Movies They'll list the best ones, the free ones & feedback on their abilities, etc. There's also related forums if help is needed.
(CyberStalker most commercial DVD's are encrypted to stop copying, so to copy them for backup purposes you need decryptor utilities.)
