Memorex's 8x DVD+R DL (RITEK S04) discs are fairly new. As the BenQ DW1620 is getting a bit old, it probably does not have support for this media. For the same reason, I don't think a BenQ DW1655 would do any better.
It may also be the media too. I have yet to find a drive that gives good results with these discs.
I just ran a test on one of the blank media in QScan and got a "This media is Not recommended at this speed" message (using both speeds 4 & 2.4). Although the graph never went above the Focus and Tracking Error threshold lines.
The Smart Test was OK at both speeds.
I think I made a mistake in my initial post. I actually used QScan 1.0 for my testing. I can't get Nero CD-DVD Speed 22.214.171.124 to test my blank media; The Start button is grayed out on Disc Quality and Advanced Disc Quality test screens.
I'm beginning to get frustrated as to what the frigin' hell is going on? Is it the test software, is it the media, is it the drive?
Is QScan reliable? or should I just ignore the verdict and burn this disc anyway?
