I have an ISO image of a video DVD that would burn as a 6.7 gig DVD. Of course I could go out and buy double layer DVDs, but it would be nice to be able to just use one of the many 4.7 gig ones I've already got. It's no problem to shrink a physical DVD to fit on a 4.7 with DVD Shrink. However, it's not a physical DVD. It's an ISO image of one. For ISO rendering programs, I have both Power ISO and Roxio. I use the latter most. Is it possible to "burn" my ISO image to the hard drive as some kind of virtual DVD and then use that as if it were a DVD with DVD Shrink to get it down to the 4.7 gigs I need to put it on a normal DVD?
