CloneDVD2's compression has been one of its weaker attributes, but, don't get me wrong here...it's still quite good. It's just that the compression you'll get from Recode, DVD Shrink, or DVD-RB will be better. But on a LOT of discs the compression you get from CloneDVD2 is more than adequate.
Episode discs...like tv shows where you have several episodes one one disc. CloneDVD2 allows you to split those into several DVD-5's so you don't have to compress them at all but still retain the menus. I use that feature a lot and love it.
