embedding media

hi. I am trying to embed a .mov file in one of my posts.

basically one of two things happens, either

a) the whole page goes funky- my layout is all messed up
b) the post is there with an empty space where the video should be

the embed code I am using is just <embed SRC=”…” WIDTH=”400″ HEIGHT=”320″ AUTOPLAY=”false” ></embed>
