It might, actually.  I'm talking about "Settings/TV 
Settings/Playback/"Over/Underscan Percentage", which stretches the 
picture using Xv rather than anything to do with the video mode.  So the 
flickering topmost/bottom-most lines would not be drawn at all.

Yes, it was not there in my original code.  It does make standard-def TV 
  look better, but I can't tell a difference on my set for 1080i material.
