I see, thank you for the reply. I can't say I've ever had any issues with my drives or Verbatim discs before but perhaps my luck ran out. I'll see if I can't get a different brand of discs and/ or another burner to test with to see if that helps.
I am using the most up to date version of this and I'm having a lot of trouble getting some games to work with this. Main thing I'm trying at the moment is Gitaroo Man (USA version); it patches in this utility without error but imgburn fails around 10% into each of the three burns I've tried so...
