I bought a premod Wii about 4 months ago and its been giving me problems non stop. When I received it the system worked fine, read originals and backups fine (both Wii and GC), then within a week it stopped working. It read originals fine but no backups would boot. I always burnt at the lowest speed and made sure the ISO size was correct. I also tried 3 different kinds of media (Verbatim, Memorex, Sony) and none did anything different. With nothing left to try I sent it back to the place where I had it modified. After doing some testing (which just involved testing their discs) they claimed that it worked fine. After some argument they sent it back and when I received it it worked for about another week and then stopped. Now its out of warranty with the place and is woefully inconsistent in playing backups (originals are still fine). It will read backups fine for a few times and then it won't. After a while it read the very same backups for a while and then stop working. Its an endless loop. Right now its it 'not work mode' and I've become disgusted with it. Thinking yet again it was the media I tried some more, made sure the ISO sizes were correct and tried 3 different burners, absolutely nothing worked. I'm beginning to suspect the laser needs to be adjusted (like back in the Dreamcast days), either that or this is a mod chip that has gone bad. Please if anyone can help, I'd appreciate it very much! Thanks!
