That's it. That's the bottom line. Thanks for making such a great set of plugins, Urs Heckmann! 
You need to copy and paste the youtube number which is found at the end of the link, in the case of Urs' video this is 3T0MlCjlSFY, then select it, then just press the youtube icon on the right of the toolbar above the text body.
Interesting. I tried with the "embed" thing from YouTube and it didn't work. Missed the button straight in the reply tool bar. Quite a nice feature.
Urs, you could probably present your videos that way in a dedicated thread, no?
