MCE GUI at fullscreen is flickering like crazy

[irondog]

I've a 915GM mini.itx motherboard with 1GB DDR2 & Pentium M 730, I've

installed MCE SP2, RU2 and all updates until June 06, latest drivers

from Intel for the integrated GMA900 chipset, but, when I run in

fullscreen MCE it flickers like crazy at resolutions higher than

640x480.

I output to a 4:3 LCD 20" TV using VGA. It seems to me there should be

a refresh rate or over/underscan problem but I don't know how to solve

it. I've played with Powerstrip in order to modify refresh rate setting

but no luck... My target is to use 800x600 resolution which allows me

to overscan image in order to fill all the TV screen. Any suggest about

how to solve this issue?

And could you explain me how manufacturers (for example Fujitsu) sells MediaCenter systems that use EXACTLY the same graphic chipset?

Anybody know which is the difference between fullscreen and windowed mode in MCE? If I'm not wrong, there's a DirectX function (exclusive mode) for fullscreen...
