i ripped my southpark dvds using dvd shrink, so that i could mkae copies for backups. i played it on the computer to make sure it worked fine, and it did. i then burned it onto a dvd using dvd decrypter. i tried to play the dvd but all i got was garbled sounds and stuff liek that. the picture was fine but the osunds were horrible. also i could not use the menus and stuff like that. i already burned like 6 dvds and now theyre all wasted. what do i do?
