Reginald, when you embbed a youtube video on the forum, you can make the window bigger :
in the embedded code, search for size informations : object width="320" height ="240" or something like that. The same size infos are available for fullscreen mode also (end of the embedded code).
Just modify the numbers with the native resolution you use for you video. You can see on the video demo I made about passing simulation, that I've been able to adapt the window size to my native resolution.
To be more specific, I used a 600px width instead of native 640px, because when you put your video on youtube, you loose some quality.
So finally, we'll be able to watch your vid in a size more matching the way you (I believe) wanted us to watch.
Great vid, by the way !
