Well, I just insert a brawl disc (japaneese version) and then two channels appeared : weather forcast and info channels.
the problem is these two channels I've already own them, I dont need them twice and plus with japaneese language...
Please help me to delete them from my Wii, I tried ereasing alla my data in my wii, starting a new page, but these channels don't wanna go...
Help me!

I think you can reformat the system, and return it to the same way it was when you got it. The option should be in the Wii settings. This will delete you save data, however.

I reformated the system... but nothing changed. please is there another solution?

Not that I can think of. I guess you could drag the channels to one of the other pages, to visually get rid of them, but those channels are inaccessible on the memory to my knowledge.

How can I drag them?!!!

Hold a and b on a channel to pick it up, then drag it to whatever space you want.

thanks! that really helps me alot!
you're so cool ^^
