No, it won't. Commercially sold audio and video DVDs are encrypted so the DVD drive can't read them unless you load a decryption key into the DVD drive. DVD players have keys built into them. There are software packages like DeCSS and libdvdcss that either have a built-in key or know how to figure one out. http://en.wikipedia.org/wiki/Content_Scramble_System http://en.wikipedia.org/wiki/DeCSS http://en.wikipedia.org/wiki/Libdvdcss Audio DVD uses a different scheme (that's also been broken): http://en.wikipedia.org/wiki/DVD-Audio > I don't know if this is what you want to do. Yes it is what he wants to do, but your suggestion is useless (as could been seen from the OP's post which showed the read-errors you get when you try to used tools like dd to read encyrpted DVDs). -- Grant
