CSS, short for Content Scramble System, is a form of copy protection with the DVD encrypted using a key only included in the firmware of "authorized" players. Copies will not be playable since they will be missing the key, which is not writable on DVD-R or DVD-RW discs.

What if you want to copy a CSS protected DVD? Better use some app to remove CSS at first, then copy it to get a free and clear DVD backup. So which CSS decrpter is easy to use and professional? Passkey for DVD is here!

Passkey DVD Decrypter is Windows-based driver which works on the fly to remove nearly all known DVD protections, like CSS, CPRM, CPPM, RC, RCE, APS, UOPs, ARccOS, RipGuard, etc.

It's easy to operate for CSS decryption. Just run Passkey for DVD, insert your DVD into DVD driver, and Passkey will analyze it. Then seconds later you will see the info that Passkey has already moved CSS and other protections (if there is any) on the DVD disc out.

Now that CSS has been removed, you can use some DVD copy software to copy this now unprotected DVD. Passkey for DVD can work with much software for DVD copy, burning, cloning, etc, such as:
★DVDFab DVD Copy
★ImgBurn (Read Mode)
★ CloneDVD
★ 1 Click DVD Copy Pro - Advanced I/O Mode Only
★ Nero Recode
★ AVS Copy
★ DVD neXt COPY V3 and 4 (without the machinist.dll)
★ DVD Shrink - Pathplayer Off with some content
★ DVDSubEdit (quick check for forced subs)
