A number of Wii users in Japan have been complaining that Super Smash Bros. Brawl fails to load or stutters during gameplay on their console.
Nintendo has deduced the problem is unclean lenses, due to dust and tobacco smoke. Brawl uses a dual layer DVD which they say is more sensitive to the imperfections.
The answer to this is simply to clean your Wii drive's lens (probably using one of those cleaning discs you can buy). Big N are offering cleaning services for free in Japan, providing customers send in their console, a warranty card and the SSBB disc.
