I'm just curious as to what would be the "best" way for backing up a DVD-5 that is 4.37 GB'S or less. I have read countless methods which use DVDDECRYPTOR'S ISO MODE AND ISO BURN MODE. I've personally used that method...but I am a little skeptikal of the burn program, so I usually back up using Smart ripper's backup option, or seclecting all files with DVDDECRYPTOR AND backing them up and ripping with Nero. My question is basically two-fold. One, what is the difference between all three of these methods, and two, is one method better then the other?

Thanks in advance
