Question about imgburn and the Sony DRU-840A in ImgBurn Support Posted August 19, 2009 It was a good burn so the disc should be playable. The only thing that may improve burn quality is burning at 4x, but I'm not sure if that would help. Have you tried that disc on other x360 consoles? Your x360 reader could be dirty or worn out You must be a genius! Cause it works like a charm now! I didn't think too slow could be a problem! lol Thanks man!
