Hello. Using Shrink with quality settings, Maximum Smoothness and Deep analysis/Compress with high quality adaptive error compensation I will go as low as 65 to 70% with no visible loss whatsover. Recode2 also a quality product sometimes requires the use of Voblanker or FixVTS to eliminate minor file structure errors first, Playing back on a 50" HD TV picture is super in widescreen. It will take longer to complete backups but nowhere near the time required to backup with DVDRebuilder using HC or CCE. I have Nothing against DVD Rebuilder but its process time IMO is like watching grass grow. By that I mean I would use a DVD-9 before I would wait for DVDRebuilder to process my backup. It is a fine product but to say that it is slow would be an obvious understatement.
