This has no aspect encoded and displayed fullscreen on a 1920x1080
monitor shows vertical line artifacts over the first 2/3 of the image.

When I say lines they are not lines as such just that the distortion
on the pendulum shows as it passes over imaginary lines at fixed
points on the screen.

with mplayer -aspect 4/3 or 16/9 it doesn't.

That one is 720x576, with a 704x576 like -

ftp://ftp.tek.com/tv/test/streams/Element/MPEG-Video/625/mobl_080.m2v

4/3 still has the vertical "line" artifacts  - 16/9 doesn't.

On other vids there is a hint of horizontal distortion, I'd need time
to cut the one I saw that on - it was subtle on a 1440x1080 16/9 long vid.
