Nope but I'd be interested in knowing what you use to put the videos up here. Is it You Tube downloader?
Nah, what you do is go to YouTube, select the clip you wish to use, right click and select 'Copy/Embed HTML' and copy. Once you have done that, return to the forum post you wish to embed it in, click the HTML button at the top of the reply box and paste the code you just copied over at YouTube.... it's as easy as that.
