I would reccomend you use what other users of "Lite-On" Burners suggest, it seems that some brands work great in some burners, and some horrible.
I have an Adaptec burner, and Verbatims are unreliable for me, unless I burn at 4x or slower.
But Bdgr says that's all he uses anymore! See what I mean?
I like Taiyo Yudens the best, I don't think I've had a bad one yet.
BTW Bdgr, just to test my theorey, what's your burner?
