My Wii is installed with wii key. Wii Version:Jap NTSC(J) I have some back ups of wii games in my com currently, tried to burn it using SONY DVD burner. Tried the following 2 types of discs so far. -OnLine DVD+R -Imation DVD-R However, it is either unable to read the disc or disc error in the middle of the game. yet...the back ups bought from shops worked out fine... May I know what's wrong with this? To be exact, What type of disc should I use? Just Verbatim DVD-R(According to related threads) or any other types? At what speed?6X or 4X? By the way, is it true that as long as wii is updated to the latest version, there won't be any problem with updating from NTSC(U) or PAL disc(required by the games)? I have spent days to sort out out the problem,please help me by providing the right info.=( Thanks a lot.
