That was a tricky one, jasjotbains.
Had to follow your link to that site then double-click the YouTube posted there and then follow the embedding deal here.
There's a sticky somewhere that explains how to post YouTube vids.
Basically, you grab the URL from YouTube:
http://www.youtube.com/watch?v=M0CV6EYMDbE&feature=player_embedded
http://www.youtube.com/watch?v=M0CV6EYMDbE&feature=player_embeddedThen you click on
.
The bracket thing appears: [ yt][/yt]
Insert only the bold faced bit from the URL.
http://www.youtube.com/watch?v=M0CV6EYMDbE&feature=player_embedded
That's everything between v= and & (if "&" appears. It's not included in all YouTube URLs.)
In other words, delete all the big stuff.
http://www.youtube.com/watch?v=M0CV6EYMDbE&feature=player_embedded
The red text (or boldfaced stuff in the previous example) gets inserted inside the brackets:
[ yt]http://www.youtube.com/watch?v=M0CV6EYMDbE&feature=player_embedded[ /yt]
[ yt]M0CV6EYMDbE[ /yt]
Like that? I zapped all the unnecessary stuff and kept the code that's needed.
Included spaces in the bracketed area so the text would appear. Normally if you post the youtube in the bracketed area it will appear just like this:
[ yt]M0CV6EYMDbE[ /yt]
Oops. Close up the spaces in the [ yt] and [ /yt] and it will work!
Good luck.
And, fwiw, if you just post a link then many people are quick to embed it for you.
Appreciated 
) but i guess your description here is the easiest way to understand and follow
