Tv-out resolution on Radion 9700 pro

I got me self a radeon 9700 pro - Evil commando2 from Powercolor.
Its got at Tv out what works fine.
The only problem is that the minimum output resolution is 1024
Ofcause I could just lower my monitor resolution but how cool is it with a
800x600 on a 19' monitor.
So is there any of u who know how u can lower your tv-out resolution (to
800x600 or maybe 640x480) while keeping your original monitor resolution
(1280x1024) ??
It seems impossible with the original drivers/software but maybe there is
some software out there that can fix the problem who knows ??
I want to capture the tv-out with a VCR while im playing one of my games so
NO! I can't just lower the resolution to 800x600 cause i can't play with
such a low resolution.
