Thanks for that chook - I see the problem, and have fixed.
Regards "add active videos" .. not sure what you mean? I'll take a stab..
If you mean "posting", then when watching in youtube, either grab the url from the top of your browser, or click "share", and grab the link there.
If you mean "viewing in a post", let me more info/your browser .. we now use YouTube's player (rather than the old 'flash player' way, which supports many more platforms .. but not yours?) ..
If I've missed completely, point me at a post that's not working for you..
