I have a problem with my new D2Ckey modded Wii... It came with an original WiiSports and a burned Mario Galaxy and both plays fine, but I tried burning Speed Racer, Mario Kart and PES 2008 and none of them are working, either I get a Disc could not be read problem or a black screen telling me to turn the power off after ejecting the disc... I'm burning them on a good media (Sony DVD-R) on my MAC Leopard running Windows XP using Imgburn... Does anyone knows what's the problem?? A friend of mine thinks it's just bad burns... Help me please...
