Hello again!

I have now bought the required eqiupment, but I have encountered a few issues;
First of all, the cable I bought is an *scart(in/out) - - 2 RCA + SVHS*. And first, I couldn't detect any other devices than my computer CRT, and when I looked closer to the package of the cable, it stood SVHS, as mentioned above, but when I called the store, they told me that S-VHS is the same as S-VIDEO, so I relay on that for now.
But still I can't detect any other devices (I have plugged the SVHS(S-video?) to the AGP, and the scart to the VHS/TV), Neither of them work. I downloaded TVtool, but that doesn't work either... I have only plugged the S-VHS plug into the videocard, and so the RCAs are just hanging.
My videocard is old, but I don't think it's too old for this.

I've tried scanning. Nothing happens - and I tried to force scanning at the startup.
In the control panel for the monitor, I klick myself into the nVidia Display Mode, where you select which device to use, but I can only choose single, and when I try using single with TV, nothing happens...
the cause of all this may be my lack of experience, but could also be lack of power, as in video card -which I doubt. But can anyone help me out here?
For faster comunication, mail is alternate, but for the sake of this forum, I don't min at all to comunicate through here...

I thank everybody in advance for help and/or corrections ! [/u]
