I installed it again, and it still wasn't working, but now I figured out why. I was testing it the whole time in the mod-forum, which is password protected, I think that's the reason, because it works in the public area.
But just a suggestion, if you now post a link, let's say:
http://youtube.com/watch?v=WufLXFlI_dM
And post it. You get the included video with the link above it. Is it possible to remove the link above the include? It would look better.
Besides that, marked as installed and gonna vote it for mod of the month. good job!
