S-Video Flicker

[sween64]

I'm connecting my Acer Travelmate 270 to an LG PAL (Australian) TV. I've enabled mirror monitors. The display I get on my TV is black and white and flickering. I've adjusted all the settings available in the SiS 650 TV Output menu (AntiFlicker Mode, Chrominance, Filter Sharpness, Colour Calibration: Coarse, Fine, Saturation). Nothing seems to work.

I'm running Windows XP SP2 with all necessary updates to software and hardware drivers.

PS: Specs for Acer Travelmate 270 can be found here.

Alterations are the:

- CPU to Mobile Intel Pentium 4 2.00 Ghz.

- HDD to Samsung HM160C

- Added 1GB of RAM to empty slot.

S-Video works fine on other laptop.
