meta: posting embeds with the new editor

Try switching to the "plain text editor" and then pasting the embed code.
If you want, you can switch back to the rich text editor and you should see a blank red box which acts as a placeholder for your video.
I tried the way you described. When I switch back i see the red box, but when I click save nothing shows up
Edit: On YOUTUBE I had to click the "Use Old Embed Code" option.... Thanks again for your help. Now I can look like a true pro with all that technology stuff people use on this site.
