<object width="420" height="297"
You can't just copy-paste the youtube url, you have to snip only that last bit that occurs after "v=" and put it after the "/v/" in the code above. The aspect ratio may also get goofy but it won't accept "width=100%" or anything like that. I'm gonna have to see what our video mod does to our posts and see if I can replicate that in the Ultimate Profile code. Until then you just gotta old-school it like the above!
