you can do a search and see several threads re what people have done to successfully backup "waist deep". ripit4me will work. and fab + vobblanker + shrink. and anydvd (payware).
edited out post here - http://forums.afterdawn.com/thread_view.cfm/2/386881#2470648 as it's a completely irrelevant place to have posted this. anyways, have teleported this thread to relevant forum. though you're not overly clear in what the actual problem is. If it's a burn problem (with Nero i can move this thread to Nero forum instead). However is the problem a burning problem or a ripping problem ?
