Don't point me to the Guitar Hero 5 Guide located here:

I tried unsuccessfully to install ios37 v3 multiple times and have not been able to do so. The other steps I have done. So please read the post fully before posting a response. Thanks all in advance!

OK, as the title of the post says, I am able to get Guitar Hero 5 to play on my Wii via Disc Channel. Usually it hangs up after the initial GH5 cartoon loading screen. I get into the game, it reads my saved files, reads from the SD card and then starts to read from the disc and then goes to the blank screen. There have been times though that I was even able to start playing (played Bush comedown for about 1 minute) and then it would go to this screen. In fact I re-downloaded the songs I purchased from Guitar Hero World Tour through the Guitar Hero 5 game all without a problem. I even bought a new song (Beautiful People)!

But it's hit or miss. Don't know what the problem is. I've got an early Wii with a Wiikey 1.9s (original Wiikey). Firmware is 4.2U and I've got HBC installed as well as Bootmii (boot2). I just installed cIOSCORP 3.5 without a hitch.

I burned the game from Sunshine Team's iso onto Verbatim media at 4x. Burning and verification went fine. What's up?! I've searched and searched and haven't found anyone who's been able to get this far into the game and THEN it goes to the blank screen. What's the deal?!
