Not to mention that CloneDVD does not handle encrypted movies (at least the early verion I tried didn't). You need to use software to defeat the encryption as it puts the DVD on your hard drive, then use CloneDVD to copy that version.
There's other software out that that costs less than CloneDVD.
CloneCD actually copies the ecryption onto the new disc if it can. That made a lot of people happy (me included).
