Hi, I get an error invalid block address when I try to copy a dvd-disk, I made a dvd with video clips using Nero 6, nero burned the dvd no problem, but when I tried to make copy of the same dvd I got an error invalid block address I'm using Verbatim dvd's my burner firmware is up to date, os winxp. Ps how do I get the error log I've looked in startsmart but can't see it.
