maineman, thanks for your reply and it’s good to be here. This forum is an outstanding resource for DVDFab users and it’s largely because of good people like yourself.
Anyway, to the point of my post. The issue has been resolved. For some reason, when I attempted to split a two-DVD set, one of which was “Part 1” and the other “Part 2”, it wouldn’t automatically divide each disk into nearly equal sizes. In this case, of course, I would have ended up with four SL disks. Perhaps it was just the way the disk was constructed insofar as it came as a “Split Set” from the distributor. Perhaps that created a problem for DVDFab in attempting to execute the Split function. (Btw, each original disk was over 6GB in size. I actually ended up burning each disk to a one SL disk compressed to 60% of the original.)
In the final analysis, I determined that there was not a problem with DVDFab 4102 when I had another original DVD that I wished to create a backup of and that disk was split fine by DVDFab, automatically allocating an appropriate size for each disk.
maineman, Thank you for your time and effort in responding. It was very much appreciated.
