Converting Film to watch on TV via the Wii

[Newbridge Exile]

One for you Tec-heads out there, a friend has given me the hangover film on a USB key in XVID Format, anyone know how to convert it so as to watch it on the TV via the Wii ( by USB or SD card)

Throw the wii in the bin. Don't see what people see in it. Go ou a buy urself an Archos 5, one of the best media players on the market. Will play anything
