Touch have resolution 480x320 which gives 1.5:1 aspect ratio, but 
panoramic DVD have 1.85:1 or even 2.35:1 so it will have black bars 
unless you're willing to have deformed picture then you can try to get 
rid of the black bars before scaling (crop video filter - "-vf-add 
crop=w:h:x:y", see "man mencoder") and then scale to 320x208
