In dvd95copy version 1.2.3 It has the option to repack evenly or anywhere from 1% to 100%. Im not sure exactly what that part is or does. Ive made a couple of test trys. I didnt notice a real difference between a repack of the extras down to 1% and a 90%. Is the difference in the extras only? Also does the size of the file matter. For example does a 6 gig compress better than an 8 gig.
