I post video on the web for personal sites and for clients. Still to date there is no viable cross platform video codec, Windows STILL does not support Flash, and Mac doesn't support WHM.
I use Fancybox to display video, using the iframe function in fancybox to get a page with the video embedded.
If not poss. for iframe loading (don't know why it wouldn't be), then I'd like a script to do that function for a normal html page.
