Hooray for homebrew! The recently released Wii Video 9 allows you to convert your video files (mpeg, divx, avi, etc.) into a playable format for your Wii. By converting the files into the MJPEG format and then transferring them to your SD Card, you can watch video through the picture channel on your Wii. The clip above is from Siliconera and demonstrates the final outcome.
The player (made by Red Kawa) is free, but you're going to want to spring for a bigger SD Card to take advantage of the program. Apparently, the conversion process increases the file size quite a bit. I haven't been able to try this out myself since I don't have a Wii, so go try it on your own and let me know how it works out. Please don't tell me what type of files you converted, though. I doubt that most of you will be using this function to watch old episodes of Buffy on the tv. (Insert your favorite Wii+porn joke here)
