First off, I don't work for Slysoft, so, this is just my opinion. However, the reason they recommend CloneDVD2 for ripping these days is because with the advent of Saw3, Grudge2, and Open Season, the AnyDVD ripper isn't working well for DVD Shrink users. DVD Shrink requires an ultra clean DVD structure, and those protections make that difficult. AnyDVD is, due to licening issues, using an older version of the FixVTS code in the Ripper portion. Apparently James has made some of his own modifications to this code, but, it's not enough for the latest protections. It still works on older titles and will work if you're doing a movie only copy of the new protections, so, they leave it enabled. However, if you want a full disc copy with DVD Shrink, they recommend ripping with CloneDVD2 because it will clean up the DVD structure. I hope this helps.
