No Thumbnails Created with YouTube Upload

I've noticed this on a few of my users where they used the "Upload" and picked the "Remove Server" and used the YouTube URL to their video...no thumbnails are created/used and there's no time noted for the video. I have to go into the video through the admin panel and put in the time, but no idea how to get the thumbnails to work.

The only way I know to "fix" this right now is I have to make the current video inactive, get the URL of the video they tried to "upload/embed", do an flv embed and assign it to the user through the admin panel and tell it the URL of the thumbs on YouTube.

How do I get it to reference the thumbnails when the user uses the "remove server" feature for uploading?
