My point was that you mentioned CloneDVD's ability to move a movie originally on a DVD9 to a DVD5 as if it were relevant to his problem. The statement is misleading and completely irrelevant to the OP's problem. CloneDVD does not actually compress the original data. It works by transcoding the video, which actually discards much of the original data- both unacceptable and impossible to implement for non-A/V applications.
Additionally, had the OP not already owned CloneCD, it would not have been necessary for him to buy a pay program to copy the DVD. Data DVDs are rarely protected, and when they are, there are no programs (including CloneCD) that can currently make a 1:1 copy of a DVD protected by, for example, Safedisc.
