Had a problem where a number of wii disc's wouldnt start properly, took quite a whille to figure out the cause, but it turned out to be due to the usb powered recharger for the wii remotes. disconnecting it was enough to enable the disc's to boot up properly. As a result the charger for the wii remotes has been disconnected from the wii and all the disc's now load. About half the disc's would load up with the charger connected, but now they all do.
