enriqueiglesias, what was the way of deleting the dupe channels? i believe you posted on wiinewz a untested method...i would be willing to try it.
Taiwanese Ritek is usually well regarded on their single layer discs, an OK-TO-GOOD on their DL media. Of course, that will also depend on your burner and the reader that you are going to put your disc on. But I'd say they are a 6.5 out of 10. Keep in mind that there are PLENTY of media in the market that I would give a 2 out of 10 and none that I would give a 10 out of 10.
So anyway, the method to erase the duplicated channels doesn't seem to work and was based on this information by Nintendo:
Delete Usage Formatting Procedure
They say:
QUOTE2) Format the Wii System Memory
This option is used to delete ALL Channels and ALL save data that have been added to the Wii console and will wipe the system memory clean, as it was when purchased new. Please note that if you also have a Wii Shop Account, that data should be deleted first (click here for instructions).
But they seem to mean all the optional channels that you created, rather than the "hardwired" main channels that already appear when you get the wii (and that includes the weather and news, even if two copies, I guess).
Also, some people found a "maintenace mode" which you access by pressing the + and - and "A" buttons simultaneosly on the wiimote when you first turn on the wii and are presented with the white health warning screen that prompts you to press A to continue.
Some rumor said that if you put your wii in this mode and then wiped all your data (store info also, etc) with a format, it fixed duplicated channels.
I have yet to see proof and don't think it works, but some have said so (trolls?
What I would like to know for sure is if upgrading to higher firmware revision does erase the channels. Some people have said "no", so I also doubt it will work.
So as far as I know, the duplicated channels are stuck forever and there is no way to get rid of them.
