It sounds like your dvd drive is wearing out or it does not like your media much. What media are you using? They say verbatim dvd r- is the best, burned @ 1-4x with imgburn. You can also try cleaning the leans, and laying the wii flat on its side with the drive on top and power button on the bottom.
