I have an output-to-TV component that requires the screen resolution to
be set to 800x600 to work.  At 800x600, video playback is jerky, but at
1024x768 it's fine.  I have a Hauppage WinTV PVR-250.  I'm running
Gentoo Linux.  Here's my info:

camille ~ # uname -a
Linux camille 2.6.22-gentoo-r5 #1 SMP Fri Sep 14 09:53:08 CDT 2007 i686
Intel(R) Celeron(R) CPU 2.66GHz GenuineIntel GNU/Linux
camille ~ # emerge -pv mythtv ivtv 

These are the packages that would be merged, in order:

[ebuild   R   ] media-tv/ivtv-1.0.2  USE="-fbcon" 0 kB 

Total: 2 packages (2 reinstalls), Size of downloads: 0 kB

Can anyone give me any advice as to how to fix this?
