Thanks for posting. I'll let you take a stab on embedding first. The links you've posted will not work as they are just video URLs generated from searching. Each video has code. For instance, everything after "v=" is the code.
http://www.youtube.com/watch?v=XtyGas7q2j0
Then use [ youtube ]code[ /youtube ] (without the spaces)... and you'll get:
• Video Link
