[plug] ddr really faster then sdram for linux kernel ?

[Mike]

Thanks Jason,

I realise I didn't make myself precise re what I am looking for:-

A linux command line utiltiy which:-

a.	Gets a selected fram from a video file and makes
	it into a jpeg

b.	Can do it 'batch' fashion for list of video files and the
	required frame numbers and produce a series of jpegs

ie. Something that will not require frequent mouse clicks to 
navigate through players to get to a known frame etc,

Rgds

mike
