When I use the DVD Shrink Program, the quality on the sliding bar (underneath Compression settings) I always left set to automatic, and then deselect all of the superfluous AC3 files that I don't need (for ex. French, Spanish...etc). The automatic quality however of the entire DVD always remains somewhere in the high 50%'s. How do I get the quality up in the 90%s? Or is this possible? Thanks!
