[mythtv-users] Asus Pundit question

[darco]

Overscan is more than just being large enough to fit the visible 
screen. Even though your pundit can fill YOUR screen, it is still not 
filling the entire NTSC frame. You may notice that you can see more of 
a picture using your pundit rather than just tuning your TV to that 
station. This is because the pundit is underscaning the video -- It is 
taking an entire 640x480 NTSC frame and scaling it down into a subset 
of an NTSC frame. Yuck.

You loose picture information when this happens. If you could put your 
pundit into overscan mode, you could disable de-interlacing and the 
picture will(should) actually look better.This is because you don't 
have to do any re-scaling or de-interlacing, which slightly degrades 
picture quality.

The CHTVOverscan option unfortunately isn't supported on the Pundit, so 
it doesn't do anything. :(
