Exporting stills from 50i 16:9 SD DV
 

I have been asked to provide some stills if possible from footage shot a couple of months ago. These may be used for menus and other items in a DVD education production. What is the best way of doing this on my set up? I imagine it needs de-interlaced?

Thanks in advance for any advice.
