elomaniak, have you tried the GCM Utility?
I have some GC isos in .gcm format. How do I burn these? Do I have to convert them somehow to .iso?
Can you try the GCM Utility? Maybe that works.
If you're using a multi-boot iso, more than likely you'll need to use GCOS or something similar to be able to choose your game.
you shouldnt select "boot dvd" but explore the disc and select the gcm or iso file you wanna launch ....
i used looneycubes multi boot iso maker

I might be wrong, but doesn't that only work for the Viper chip (for the GC, not Wii)?
