I've read this is quite a problem. But I believe mine is a tad different and this is why I'm bothering to ask about it. The first GC game I've burned (Path of Radiance) works perfectly. I used a TDK DVD+R (1-16x speed) burned at 3x speed. Played a few hours, all is well. Except now imgburn won't burn any more ISO. It gives me an error somewhere around the end about I/O or something like that. I forgot the whole message exactly but I could scrap another disc to take a screenshot. I tried burning again on another computer with imgburn also, and the same CD. The burn goes fine, but it doesn't work once in Neogamma. (DVD+R/bad burn/DL problems?) I believe all the settings are the same. I also made sure all ISO worked in Dolphin.
