I have recently run into a problem. I modded my Gamecube with Qoob Pro way back in early 2005 and I NEVER had problems burning working ISOs.
It has been about year since the last time I burned anything for Gamecube, and now I can no longer get them to work. The Gamecube tries to read the DVDs, but they just fail to boot. All of the DVDs I burned last year are still 100% working.
Info:
-Burner: Pioneer 109
-Media: Ritek and TDK media (both of which worked for me before without any trouble)
-Applications used: Nero 6.6, Nero 7, ImgBurn, and a few others
I've been trying to burn Zelda Collectors Edition, and Bleach. The ISOs are the correct 1,459,978,240 size.
The weird thing is that PS2 ISOs burn and work perfectly, I am only having trouble with Gamecube.
Stinkycube releases gave my GameCube hell and never really worked properly with my qoob Pro, even after tweaking the pot, which is probably why my GameCube's laser died so quick (twice). Ended up getting a new GameCube altogether and stopped using Stinkycube releases.
