thx guys... did some web research and i'm looking into buying a capture device that plugs into my firewire port... I don't want a PCI card because I want to be able to use it anywhere.... they look like they're around 200 bux for something that will convert the Wii's analog output into digital video input, on a computer in real time (basically the same as a card that lets you watch TV on your computer). But a box, rather than a card.
fyi: I'm really getting into the Mii art, and I've gone live with http://www.showmii.com. If any of you would like to contribute it would be awesome. So far there's just my gallery up, my 8 favorite Mii's. I'll start off just posting Miis of anyone who sends screenshots, and eventually build an index of celebs, with all the versions of the character that have been submitted, a voting system to decide which one is the best version, a 'best alltime' section, how-to pages with videos...
Can't wait til everyone opens their Wiis on Xmas morning, this thing is going to blow up huge!
Also, would anyone like to submit Miis to use on the logo at the top? The photography on mine are too low-quality to use for a logo.
