I can`t either. 
Resolved: Video embed is glitchy in new format
Ok, I got it finally.
Step 1 - go to youtube.com and sign in
Step 2 - find the video you wanna post
Step 3 - click the SHARE button
Step 4 - click the EMBED button
Step 5 - Use the "old embed code"
Step 6 - Copy the code provided in the box

Step 7 - Paste the code the way you used to paste the URL.
Hope that helps.
