I've just started using ImgBurn today, and its really the first time I've tried to burn ANYTHING. I'm using an older drive and mediocre CD-RWs, but I'm not sure that's the problem here. I'd heard that that would destroy the disks, but these disks still work fine. They're just empty. When it tries to verify after the burn, I get "Layouts do not match". Don't know what that means. Can someone tell me what's going on here?
