One of them is the original program, the other is a parasite that tries to make money from others hard work.
If you want the real thing go to slysoft.com or elby.ch and purchase the program of CloneDVD2 there for 39.00 U.S.. Elaborate Bytes a bit more expensive at 39.00 Euro. Want a combo package, get latest versions of AnyDVD and ClonedDVD2 for 59.00. You will need AnyDVD to remove the copy protection for CloneDVD2.
If you want the inferior parasite version you can spend your 100.00 and get CloneDVD at Clonedvd.net. Copy protection removal is done within.
I just don't understand why Elaborate Bytes and Slysoft permit this name infringement.
You can spend 59.00 and get outstanding software that keeps up with the ever changing copy protection in terms of days, not weeks or months.
Or you can buy the software for 100.00 that has less capabilities and draws revenue by deception. The choice is yours, my vote goes for Slysoft and Elaborate Bytes.
