hi I have just bought a pilates exercise dvd and am trying to back it up (it was expensive) .I tried using dvd decrypter but it says it will take 74 hours and thats when it actually picks up the dvd and then I'm getting CDB errors too which I have no idea what they are .On the front of the dvd packet it has English pal written on it I dont know if this matters or not .also some time when I put it in the drive it wont pick it up or play it,but it plays fine on my dvd player mandy please help me
