Well, have to say that I'm not terribly impressed with this plugin. The ease of use is nice, I suppose. However, if you are able to grab the URL for the video from YouTube (which is all this plugin requires) then you are as equally capable of grabbing the embed code. And the plugin just goes ahead and inserts a thumbnail and link back to the YouTube page for the video when you access the post via your RSS reader. I know the documentation indicates some readers won't display correctly, however, the embed code from YouTube displays correctly in Google Reader.

Oh, and the selection of border color doesn't work in the plugin either. Bummer.

Going to have to give this a fail for my use. But if you're scared of copying and pasting embed code, give it a shot!
