I'm trying to backup all of my DVDs to ISO files. I've been using ISORecorder but there are several DVDs that I'm unable to copy (e.g. 'Romeo + Juliet', 'Gladiator', etc.) The problem, I think, has to do with these discs having some sort of copy protection on them; using ISORecorder doesn't produce the desired effect.
Is there a program/process by which I can bypass some of these 'features' to rip my DVDs to ISOs? If not, is there a file format by which I can convert my DVDs to that will retain all of the features and that can be easily converted back to a DVD disc format?
