Try playing the game on a WBFS file with a USB Loader instead as that will have the least amount of issues and no disc read errors.
Also here's a little trick for the Wii Remote Plus I managed to find out for Skyward Sword: If you ever start experiencing motion problems, pull out your sword and slowly swing it around clockwise (just found it easiest to do) and it will fix itself. You should almost NEVER have to open up the menu for callibration.
