Ok, so far I have about 12 or 15 games that work absolutely perfectly. But three recent games that everyone has been really excited about suddenly working perfectly I can not get to read at all.

My Wii is USA, NTSC 3.2U (with SafeUpdate installed)

I've updated my IOS249 to wiigator's rev 7, I've tried using several gamma channels as well as the gamma HBC loader, and with the reboot hooks..

I'm burning on TDK DVD-R Manufacture ID: CMC MAG, AM3 (I've never had a failed burn on anything EVER till I started dealing with the Wii backups)
http://www.digitalfaq.com/media/dvdmedia.htm (rated very high quality on there)

Burning with ImgBurn & verifying
I've tried all various speeds

My ISO's are all 1:1 (4,699,979,776 bytes)

The three problem games are:
Boom Blox (NTSC, USA)
Da Blob (NTSC, USA)
Super Paper Mario (NTSC, USA)

I've been scouring the forums for days now trying everything I can imagine and every single tip I've read, and still can not get any of those discs to read. I've tried removing all cIOS with anytitledeleter, installing ONLY rev7, using wad packs to install, etc... I'm at my wit's end.

I really can't believe that it would be the media causing the issue considering so many other discs work perfectly and flawlessly, and I've tried re-burning all three of these titles several times each, all at various speeds and all with the same results. Though plenty other titles burn at 16x and work GREAT...

Any and all help would be greatly appreciated. I'm willing to try anything at this point. I've killed 20+ hours trying to fix it on my own, and no luck.
