Fuze+ Video Requirements

hi. i am using ubuntu 10.04 ond have  winff w/ the extra lybsincodec package. can someone please help me with a step by step “for dummies” of how i can convert video for the fuze+? i tried to do the command line commands but didn’t get very far. help using winff and it’s gui would be awesome. the winff forums are down or i would ask over there. thanks so much if anyone can help.
