YouTube seems to have changed the way single URLs of their videos work so instead of being:
They are now:
With Smart YouTube you had to put a “v” after the “http” of the URL for it to embed the video in your site with correct width and height measurements. After the YouTube URL change this no longer works. Is there another way of doing this now?
i had the same problem Rob and so I just use the url in the address bar instead of the shortened share link youtube provide. I see the plugin provider Vladimir said 2 weeks ago to user Mark Tyson asking the same question:
This is not supported yet, you should just use the youtube.com URL from your browser address bar.
So until Vladimir changes the Smart Youtube plugin it is all we can do.
