I had OneClick DVD Copy 4.2 and
AnyDVD installed so it cost me $39.00 to buy using the registration code of 4.2. It looks like it has the best aspects of
DVD95Copy and
CloneDVD2. On CloneDVD2, you can review each title and choose to eliminate a title before you make a copy but you can't regulate the compression on each title. On DVD95 the extras are compressed automaticaly (can change) to 30% and the main film is then compressed to fit the remainder of a DVD5. But there is no viewing screen. So you guess what is in each title. On OneClick DVD Copy Pro you can view each title and can compress (within limits) or eliminate any title.
I prefer to eliminate all "Coming Atractions" and keep the extas about the making of the film. However I will compress these extras quite a bit and use the automatic setting on the main film. I havn't had time to actually try it out yet but I have had the initial OneClick for about a year and a half and I liked the quality, ease and quickness of its copying.
