"Character walking" doesn't sound like a beginner's job.
If it's supposed to walk all over the browser window (I guess this is what
you mean by "host sites page"), video with alpha channel is not an option IMHO,
this will use much too much bandwidth.
You will need to generate a few keyframe sequences for steps into different
directions, then replicate these with actionscript to simulate walking.
Depending on whether we're talking about an animated "character" or a real-life
character, this could either be done with short video loops, pictures or all
drawn by hand as in cartoon animation.
To make it walk "all over" the window, you will need a stage size filling the
whole browser window, with wmode=transparent, probably causing some browser
display problems, unfortunately.
The alternative route I could see is a short video loop (the way you probably
thought) of the character walking in the same place, which is shown in a small
Flash <object> (not much larger than the character itself).
This small Flash object would be inside a <div> that gets cleverly
repositioned by javaScript. Don't expect Dreamweaver to be able to help you
with that though. This requires careful hand programming both in Flash and in
HTML/javaScript.
Probably try to simplify the request. It would be a lot easier if the walking
could only happen in a defined horizontal space, e.g. walk across a banner.
Good luck
