I didnt want the stretch per se, but to avoid losing info because of the
letterboxing (the final project involves reading small print from film
credits on the captured MPEGs). But Daniel wrote that the 16:9 analog
broadcasts have only 432 lines, so the info is not there in the first
place. So that effect isnt an option for me. But thanks anyway.
