A couple of things. That is the right test. First off, I'm guessing that wasn't scanned on the liteon. In the future, use your liteon drive for scanning. Second, under settings speed, select 4x, not maximum. At the top where it says atapi dvd ls.... That is where you select the drive to scan with.
Reguardless, it would seem that acording to the top graph (pi errors), that disk burned very good so burn quality (with the verbatium at least) is not your problem. On the bottom graph, I asume that the drive could not report pi falures, thats one reason to use they liteon, they can report pi falures. If the drive can infact report pi falures, having no errors is very rare (an exceptional burn), but I would be more liklly to think it cannot report pi falures so use the liteon. Maybe next time try scanning one of the cmcmage01 disks that you have already burned to see how it did?
Also, try to keep track of what disk was originally burned on what drive. It's possible that one of your drives will like a particular media but the other wont.
