if anyone was clueless about watching videos on the wii, you are able to, once converted, watch videos with the photochannel. I just tryed it out and it works pretty well.
the format you must use when encoding is thus
pcm or ulaw
and decrease the audio and video quality just a bit for optimal size and viewing
i used a 1 minute 10 second video snip from when I was editing some brawl videos. feel free to have a look.
