Works quite fine, only a thought!
You could add a routine to your video fetching code so that a user won't have to enter the exact embed code but also the URL code.
For Example:
http://www.youtube.com/watch?v=3RoTCFWstF4&feature=rec-HM-r2
Actual embed code
http://www.youtube.com/watch?v=3RoTCFWstF4
So just strip everything (including) after the "&" symbol in the string the user submits. Will help alot
Remember, users are thick (yes, always)
