Ok then i had to get a FLV player..
I got this one at cnet.com -
http://download.cnet.com/FLV-Player/...-10467081.html

just download it and install it
then go click your downloaded flv video file and it will start playing it right away - it did on my computer anyway.
i tried another program but it had a lot of other settings and was a much more complicated install. This one is pretty easy.
