Configuring Acer Laptop for TV out using S Video

Hi,

I've spent the last 2 hours trying to set up my Acer laptop so that I can play videos on my TV, to no avail. I'm using an S Video to Scart cable, and the audio is working but no pictures, ive tried ctrl+alt+f2 which didn't work, so im pretty stuck.

Any ideas would be great as it cost me £12 for the cable, and i don't want to give in to this bloody computer

cheers guys
