I verify everything for peace of mind, but I burn with Roxio & use fab only to rip. Roxio verifies much faster than fab, and I have a 100% success rate with verbatim +R blanks & panasonic +RW rewriteables.

the only exception to that is on the rare occasions when I want a DL burn, then I let fab do everything, and just go away for an hour or so while fab does its thing. It could be that Roxio would do those OK also, but fab knows how to do the layer break thing which is the trickiest part of a good DL burn.
