I wish to back up my DVD of "The Wild Bunch" which is a flipper! Is it possible for it to be converted to a dual layer disk? if so can someone give me the instructions on how to do it. My burner is an LG GSA 4167B with the lastest firmware updates installed, I have a registered version of AnyDVD running plus DVDShrink and DVD Decrypter. Any help with this task will be greatly appreciated.
