This process is getting to be more expensive and a time waster than it’s worth. I’ve wasted about 15 DVD-R’s and countless hours now trying all different ways of backing up DVD’s. From Smart-Ripper to IFO Edit to DVD Shrink and then to Nero 6 telling me I had a “Burn Failure” due to Buffer Underrun, Can’t close disc, etc. I’ve used up all my patience and will simply buy the damned things from now on. There are simply way too many variables and it seems to me it only takes ONE to waste your time and money.
P.S. Roxio sucks ass too because their DVD Builder App always encodes ALREADY ENCODED files.
