1. Because its accessing via the GC mode, the wiimote will not work, and I havent tried with a GC controller but the only way would be using the reset button
2. IMGBURN is a must ! The other factors can be the burner, media and burn speed.
4x seems to be the most stable speed to use for the majority of burners, slower can cause issues, and so can faster. If getting Verbatim try to find made in japan or singapore, if getting TY get the premium line not value.
