Thanks again for the reply!
Could be poor media, I suppose... I would sure hope not, though...
When I run a writing test using cdspeed, it ramps up pretty steeply, and then when it gets to 24x it just immediately flattens out. I've tried it with 3 different discs from the stack, and they all start off great, and then lock at 24x (actually just under at 23.92x, every time).
It seems as though there's something other than the quality of the media that's limiting it, unless the media somehow tells the drive a max rate. If it is due to the quality of the media, wouldn't it be more likely to have at least *some* variation in the performance of the drive?
Also, I used cdspeed to create a data disc (which burned at 24x using the same media), and then used the cdspeed quality test on this newly created data disk. Surprisingly, I didn't get a single error, which indicates (at least to me) that the media may not be as bad as I was beginning to think.
Sorry if I seem a bit clueless about this stuff -- it's because I am!
Thanks for your help!
