by adding a youtube video you will receive this error:

Invalid Youtube video URL:[url]http://www.youtube.com/watch?v=wBJhLtvG1rM[/url]

but you can see that this video exist. Bug is in version 2.01 +

will check it, thanks for the report.

That Video was deleted by Youtube due to law issues.
This is not a Bug.

I am also getting the same problem in 3.0.2
