I've come across a rather grating problem on my fall break.
I've just plugged my Wii-U in after leaving it by itself for a couple months, and rented two Wii-U games from GameFly recently - Zombi-U and Batman: Arkham City - but neither of them want to work. Zombi-U gets stuck on the splash screen when I select it on the Wii-U menu. Batman gets a little further, but when it reaches the start menu, I keep getting the same "Disc can't be read" error screen. If I keep removing and inserting the disc like it instructs, it eventually says the disc has been removed and makes me shut off the system.
The strange thing is this is only happening to these two games at the moment. I also have NintendoLand and NSMBU, and both seem to run fine. It's also not a problem with the discs themselves because neither of them are dirty or scratched and I cleaned them several times. Could this be a problem with something inside the Wii-U, or am I just unlucky enough to have rented two faulty discs at the same time?
