used decrypter to decrypt a movie and then shrink to shrink it down. however, shrink didn't make an ISO out of it. instead, the files types were BUP, IFO and VOB. I then burned those to a blank dvd (using roxio) but it wasn't playable on my computer or dvd player. the files were all there but it didn't work. can anyone help? i have decrypter 3.5.4 and shrink 3.2 (latest versions). or do i have to use a certain program to burn these BUP, IFO and VOB files to a blank dvd?
