Hello. refer to the countless posts on this forum. i'll summarise. use v good media, burn at 4x (its not like its slow, even on a real fast burner), maybe set the rip size to 4300mb, no multitaskin (during burns). Maybe check firmware rev of burner, but only update if u know what you're doing. Lots of peepl say check/sort out the aspi layer. Oh and if you use Nero, be wary of 6.6.0.1 thru 6.6.0.5.Many, many threads on this subject by the way.
