Thanks.
I think I should worry though, because the reading performance is, to put it nicely, shit:
ALL read tests look the same, no matter what discs I use. Even the discs burned by the Pioneer drive I know are in perfect shape look like this.
I just popped in a friends LiteOn SHW 160P6S, and the burns and reads are perfect. Therefore my conclusion is that there's something fundementally wrong with the BenQ drive.
Suppose I don't have any other choice than getting a new one then. Which one is recommended? I burn alot of discs, and "perfect" burns is very important to me.
