If you only copied and pasted the URL, then where is the title of the video coming from in your post.
I copied and pasted the URL from the top of the video on YouTube and I have no idea where the title of the video is coming from.
Ok, how about this. In the box where you type your post, click on the icon above that looks like camera film, and paste the URL in the popup box, and then click the embed button. After that, hit the Post Reply button and let's see if that changes anything.
That just worked for me. I was doing as you suggested in your first response to me with no difference, so I guess this is a work around that. Who knows. Thanks.
