TEchnical advice needed

[GalDisney]

I made a "movie" of the MK that I want to post on you tube. I am able to post it but it says something about being a wrong file type and it wont play. I used microsoft movie maker, like you tube says. I tried posting on my space and no luck either. It is a "movie" made from stll photos, but that shouldnt make a difference, should it? Any help would be appreciated as I would love to post my MK movie for other disney fans to see.
