I'm glad to see embed FLV becoming more accepted. I'll have to try that on some freesites.
If you're thinking of doing FLV, check out the Sothink Flash Encoder. I've been playing around with it, and it's pretty amazing. Not only does it convert your video to FLV, but it also creates a player, a preview thumbnail, and the HTML code. Costs $45, but there's a free trial.
