Technically challenged user. Can't view video thumbnails Help

I’ve been searching all over the internet about the problem with not being able to see the video thumbnails. Instead it just shows the winamp icon or windows media player icon. I have “unchecked” the option to “display icon instead of thumbnails”, but it still does not work.

That’s because Twonky media server probably doesn’t do thumbnails for video files.  Check this LINK out and see if it will work for you.
