i was using dvd shrink and trying to copy a dvd. it would stop when it was analyzing and the error cyclic redundancy message would appear. i defragmented the hard drive and then it worked fine. then i tried to do another dvd. the error message appeared again. i tried defragmenting the hard drive again, but this time it did not work. i took the same disc i was trying to copy to my uncle's computer and it copied fine. i cannot analyze or encode anything now without the cyclic redundancy error. i just bought a new lite-on 16x dual layer drive and made about 15 copies with it before the cyclic redundancy error started. the media i was trying to copy from was a 4x verbatim dvd+r that i made using dvd shrink. PLZ HELP!
