I've got a Wii console that was originally set up for the 4.1u system menu. My kids got two new DVDs that would not play: Skylanders and Tangled. The error is the Disc Read Error. I thought, perhaps, it was a mod problem, so I've spent much of today following steps to update the system menu to 4.3U, as well as the CFG Loader. They still get that error. Running CFG Loader and copying the disc gets VERY slow at a couple of points, and then the image won't run after it's completed. I'm assuming at this point that it's a bad DVD, but didn't want to spend the $$ on one if it's something else. Any help would be greatly appreciated (and my kids would be thrilled!) Thanks!
