Video screen shots/capture

Can anybody tell me what software is best to use to capture quality screen shots of you MPG/AVI/etc. files ?.

Something that you can set the output path, start playing and then click away !

I think the easiest way is to play your file in Media Player Classic and press F5 when you want to make captures. (This doesn’t seem to work with QuickTime files for some reason though).
Go http://www.gabest.org and follow the links to get Media Player Classic.

Works perfect, thanx

Talking about screen capture tools, I can advise to try Screen VidShot, which takes video screen captures.It allows you to record capture to avi,asf,wmv.You can find it here:
