It wouldn't be hard to tweak my uploader to allowing mpg, avi or other video files but I did run across a question. I need to have a thumbnail of the movie (like how Youtube has) and was wondering if there was a module that could extract either the first frame or a frame at a specific interval that I could thumbnail.

I've done something like that manually with ImageMagick, but in that case it was and ad hoc job and I wanted to visually pick "significative" frames. I suppose that it would be relatively easy to automatize the process with Image::Magick.
