I can't seem to embed Youtube videos in comments anymore, does anybody know why this is? I've tried every which way possible but nothing seems to work. Other Sifters seem to have no problem doing it.

(1)...... Using the basic embed code
(2)...... Submitting via "Bookmarlet", copying THAT full code & trying to submit it.
(3)...... Trying both of the above using the OLD embed code.

Feedback here please people.

Thanks.
