XnView Software

I have found Xnview's extract movie frames to be a very handy tool. Most software barfs on mpg's, but here xnview works flawlessly. I'd like to see a way to extract frames from multiple movie files at once...

any thoughts?

XnView is mainly for image\picture management, the extract feature in XnView 1.90 alpha 3 only does single clips for now.
Changing this feature would be a major job but I'll wait and see what Pierre says.
