Just a quick entry, I created a simple flash movie player the other day that can be embedded into an HTML page and play flash movies.
The embed code is simple
<embed src="mplayer.swf" type="application/x-shockwave-flash" id="mplayer" height="320" width="240" flashvars="vf=/videos/mymovie.flv" ></embed>
The height and width can be changed to suit and the player will re-size itself, the movie to play is specified with the flashvar vf.
The player is attached to this article as a zip file.
