I have an NTSC Wii but am in the UK.
Can I install the BBC Iplayer on my Wii?
Mmmm... I doubt it actually. You have to download it from the shop channel, can you see it in the shop channel? I don't know how the shop channel works, if it's location based it will look at your ip address and work out you're from the uk and let you through. However if it looks at your version of the shop channel and works it out from that, it will think that because you're using the ntsc version of the shop channel that you're not from this country.
