Bought some games for the Wii while in Thailand, but can't play them. Shop I bought them from assured me they were "multi-zone" and will play in NZ, but turns out they are NTSC and won't play on my new NZ Wii.

Checked out  the Datel Freeloader, but since the Wii is new ( Version 3.3 ) this won't work either.

Is there an easy method to rip them to the computer HDD, convert them to PAL, then burn to blank DVD ?
( The PCs DVD drive doesn't seem to recognise the discs ) ?
