And you watch with mythtv again? Myth sets these values every-time it
starts recording. Try to use cat /dev/videoX > test.mpeg and play that.

I found another control that actually sets the aspect ratio.
 v4l2-ctl --set-ctrl=video_aspect=2

And check with v4l2-ctl --log-status.

I am not sure but I though ivtv detects this automatically. Maybe
someone can confirm this or tell me how wrong I am ;-)
