I would be VERY interested in comparison's... I think a lot of people are. In fact, if someone has a guide or something for a good way to compare these programs and display results, send them to me and I would be happy to play.
In CloneDVD user's defense, CloneDVD may be one of the easiest programs for copying DVDs. Don't give the users too hard of a time for not caring too much about quality. Also, if you already paid for a program, you're going to use it right? I think Elby has a great team, and they are putting out great products. (What is this Makedisc on their site?)
I have a friend that was using DVDXCopy Platinum, he would not consider anything else because it was simple. When he had a problem with Xpress only copying the menu or something, I showed him CloneDVD and he said "wow that's way easy".
(I know nobody cares, feel free to ignore me)
