Winfast Card To Tv

Hey,
how is it pssible to connect my tv to my computer using my winfast tv card? I have to use the red,white and yellow cables?

Yellow stands for video, red stands for right audio channel and white stands for left audio channel.

i know where the cables go in the tv but where do they go on the computer end?

The yellow plug goes in TV out and the red & white plug will go to audio out of your sound card.

ok ive hooked all the cables up but how do i make the tv my main monitor in windows? im using XP.
