Question about tv-out

[SimplyComplex]

If I have a D-Sub video card with tv-out will this work as a medium to my very old tv?
As far as I understand, it should. But someone on another hardware forum tells me I must buy an $80 vga to composite converter box. The trouble is RCA *is* composite, so I do believe the $12 item I'm wanting to buy already does what I want.
As I understand it, tv-out converts the video signal to interlaced. So I'm missing where this would fail.

Frankly $80 is more than the old P3 I'm wanting to use as a media center is even worth.

WHy not just buy a 18$ card like this, it come with the connector you need, I believe.

What card do you have now?

I have several. I have an AOpen Savage Pci card. I have an ATI RagePro 128 Xpert2000(32mb) and an NVidia MX400. They're all D-Subs.
My tv is not S-Video compatible. It only has a coax and a composite(RCA) connector.

I don't see anything about the card you posted that would allow me to attach directly to my tv. Also, the system I was planning to use as a media center is a 1ghz P3. It has AGP but no PCI-E.

I was just unclear if a tv-out card would provide a compatible signal if an adapter to composite video were used.
