I've been using Decrypter and Shrink for a while now. I upgraded from 321 Studios DVDXCopy Platinum. I've noticed there is a plethora of software available on this site. What is the advantage of Decryptor over the others? What is the advantage of Shrink over DVD2One? What is this Gordian Knot thingy? I can re-author with Shrink why do I need IFOEdit? Is there a good comparison chart that would help me decide which software packages would be best for me? Thanks,
