If im using a dual layer burner whats the best way to copy it. can i use dvdshrink with no compression and then burn the decrypted files with nero? will I loose any quality that way? My second question is, If I wanted to burn to a 4.7gb dvd what the best way to compress the dvd, in terms of quality? I know dvdshrink can do it but hows the qualityt? is there a different method that outputs better quality? thanks for your help.
