Any way to auto generate thumbnails for AVI movies?

[kelemvor]

So I rip all my movies to AVI files and name them with the movie name (e.g. Iron Man.avi, Star Trek.avi, etc) and have them in one, big folder. I've recently started using Windows Media Center with my Xbox to stream them. I'm trying to find a way to get thumbnails for the movies to show up.

I saw that if I put each folder in its own folder and name a .jpg as the name of the folder, or something like that, it would work. However, that's a pain in the ass with 100+ movies. Is there any easier way to do this like the way Windows will go online and download cover art for albums and such?

Thanks.

Search in tools here.
Media Player Classic for example, will do it.

If you have Windows 7 or Vista, you can use the Media Browser plugin for Windows Media Center (works fine with the Xbox) along with Metabrowser to automatically organise and download the cover art.

Heres what it will look like.
