It's working fine for me but the width/height attributes aren't fond of percentages, perhaps it only wants pixels? Would be nice to have a note about that if it's true.

Its not working for me in IE7 without using the width and height attributes.

It would be nice to have a picture shown before the user clicks...

FLV player seems to enforce a fixed ratio for your videos... More unfortunately, this seems to be some weird ratio that is not 4:3 or 16:9. When I set my video to width=300, height=225, my video's height become 225 and width becomes shorter, something like 270 or so... If I set it to 300x250, it turns itself to 300x243. I really don't know how it works. Why can't it just let us set whatever width and height we want?

[edit] Adding a Video Description Dynamically

How do I autopopulate the box containing 'Change this error message for enabling JavaScript and having the latest Flash Player plugin installed in: deploy/index.html' with the video's description? It's obviously not as simple as editing the title with t="video title".
