You would think. But it wouldn't even attempt to burn on the +R

It depends on what you're burning too. The files I'm running only work on the -R, when I tried +R they wouldn't even attempt to burn

I just got the same error message. I'm new to imgburn, but the first time I used the program it ran fine and was successful, but the 4 discs since then are ruined due to this I/O error. Is it a problem with a faulty burner?
