I would like to copy a dual layer dvd to a single 4.7 GB disc. I have the appropriate hardware and software...a LG 16x dual layer buner and dvd crypter. I have set dvd decrypter to selct main movie files and the IFO but when it does this the final size comes up to 7 something GB. Is this ok. If not can it be corrected and how?. Thanks so much for all you help.
