Best thing to do is to put up the URL w/o the http://www on it.
Why no www?
ONLY for MySpace Videos!!
The Embeding package we have running on the forum tries to auto-embed video's so people cal view them from the thread and don't have to click on a link.
Well Myspace is dumb and doesn't let 'this' package do it. We found another that does do myspace but it broke YouTube...figured Youtube was more important
So if the package can see it is a site it will try to embed. So you've got to pull a bit more information off or you'll just be going around in ciricles trying to get the url to show.
