DVDrebuilder has matured and grown into a top notch DVD backup program. With CCE basic it is the lowest cost truly high end encoder based setup. But there is always the desire for more. Some with CCEsp like performing additional passes to improve slightly the distribution of the lower bitrate encodes. I personally do not own SP but I do periodically run the latest SP trial to see what I am missing. I like 1 pass VBR for the time savings. I would pay extra for this if it were available seperate but not for 2000 dollars. My experience with 3,4,5... on up passes have not given me anything useful for the additional time on DVD backups. People with bigger screens and more time on there hands may differ in opinion. Let find out who has CCE sp and has tested the boundries of quality with additional passes. If you feel the time is worth it say so here. What quality settings and DVD sizes and types are used.
