I backup using DVD shrink but rarely compress anything and never below 90% when I do. For those of you that compress, what kind of quality loss could I expect if I compressed to say 86% or 80% and used Deep Analysis? What point should I not compress to regardless of deep analysis (60%, 75%?) I want my backups to be as close to the orignals as possible with little to no loss in quality. I thought I would ask instead of wasting a bunch of blanks doing tests. Thanks.
