Lean Video Cropping

What’s a really simple and lean video cropping tool?  Basically I want to snip a minute or so of video out a a 30-60 minute video (and perhaps even off a DVD). 

At the resolution I needs that amounts to about a 9.5 megabyte file.  But most of the video editing tools I have found are far to complex (and too slow) to do exactly what I am looking for. 

Anyone have a good suggestion for a lean, green cropping machine?
