S-Video not working on ATI Radeon 9800 Pro????

I've had this ATI Radeon 9800 Pro in my MDD dual 1.25 G4 for a little while with two VGA monitors. I recently got rid of the secondary monitor and moved a 27" flat screen tube TV next to the computer. As I always do, I've got to start tinkering. I remembered that my Radeon has both VGA, DVI, and an S-Video outputs. I simply ran an S-Video from the card to the TV. I can't seem to get it to work. I had never used the ATI control panels so I went ahead and downloaded and installed it. It won't "detect" the TV in the Mac2TV control. What the heck am I doing wrong???? I emailed ATI and they just sent me a form reply to a dead link saying that my system is unstable. UGH!

Any tips would be great.

Thanks much,
Robert

Well, I figured out that if I reboot and only have the s-video attached and no monitors to the VGA or DVI it will work. It dedicates the TV as the primary screen. However, not the best picture. I can't find any information if both the s-video and VGA or DVI can operate at the same time. I'm also doing a little more research with ATI to see if they actually have a true component output from either the VGA or DVI. I had bought a DVI to what I thought was supposed to be component but it was actually RGB component and just gave a distorted image. If I can get that to work, I think it would be a better image along with being able to run both the monitor and the TV as the secondary.

Hi Robert-

Progress is good....
This article mainly addresses s-video out in XP, but, it could give you some food for thought to apply to your situation.

My understanding is, that rather than use as a monitor, per se, the s-video funtion is more for watching DVD's and such.

I use a TV connected to a QS, but, that's connected with DVI to HDMI. Nice desktop, and movies look great.....
