TV Box?

On Altavisto's recent trip to Nipon, he bought a fancy Tv Box for converting a composite cable to VGA, so we could play our game cube. It's pretty cool and it seems to do many more things than just this conversion, like possibly TV tuning etc. This all seems pretty cool except.... the manual is in japanese. So we can't figure anything out!!!
The inhumanity :-P
ps. any japanese out there that want to help us?!!!
