have found that most dvds i try to decrypt using various programs (dvd decrypter, xcopy, dvd shrink, clone dvd)can not decrypt them. when i use dvd decrypter which i mainly use i get a read error either at the start or around half way. i no that its not the movies cause my friend can decrypt the movie on his computer. Do you think its my burner???? or is there just some movies that are too scratched that only dual layer burners can read...i have no idea. Also when i burn froma burnt dvd i have already burnt it dosnt play on my dvd player ... once again is this just cause of the dvd burner i am using not being good enough???
