Hello,

I running MythTV on Debian 3.0 with Hauppauge PVR350 and TV-Screen. No 
Monitor else connected to the box.

My problem to see not all of the X-Window and also not all of the tv 
playback on the tv-screen.
It seems the resolution used is 800x600 but my television have only the 
resolution 720x576. Therfore I can not see 60pixel at one and 24pixel at 
the other edge.
Here you can see an excerpt of my /var/log/XFree86.0.log.

74.5 Hz
(II) IVTVDEV(0): Modeline "720x576"   41.48  720 752 840 928  576 580 584 
600 -hsync -vsync
(++) IVTVDEV(0): DPI set to (100, 100)
(II) Loading sub module "fb"
(II) LoadModule: "fb"

How to scale the display size (800x600) to the given hardware size (720x576) 
both for the TV rendition and for the x-screen?

Thanks for your help
Matthias
