[help] Dual-Head display

[Krpano]

I have my TV conected to my S-video out and its working properly (almost), because i can see a clone(its what i need) of my desktop there but it is displaying the same resolution as my primary monitor (1152x864).

My question is, how could i modify my xorg.conf (see below) to make my TV work with 800x600 resolution ?
