TV-Out troubles on a Radeon 9600 pro with s-video (7 pin?)

[Anon]

I recently upgraded my system, which included a new Connect 3D Radeon
9600 pro video card. When I went to use the tv-out port to connect my
PC to my TV, I couldn't get anything to display, and in fact the card
wouldn't even detect that it was plugged into the TV. I used the same
s-video cables that worked fine with my old card, but it wouldn't
work.

To test if the port was defective or not, I used the included s-video
to composite converter to hook up to my TV, and it worked fine. But
obviously the quality isn't as good as pure s-video, so I would like
to figure out what the problem is.

In comparing the s-video converter with my existing s-video cables, I
noticed that my old cables have the standard 4 pins, while the
converter has 7 pins. Is this what is causing my problems? Is there an
easy fix, or do I need some sort of 7 pin to 4 pin converter? Thanks
for the help.

I am experiencing a similar problem with my 9800 pro. Using the ATI provided
S-Video to Composite adapter, which has more pins at the S-Video end than
I've seen on normal S-Video Connectors, in conjunction with an expensive and
high-quality composite video cable, I achieve much better image quality to
the TV than with an expensive( $50.00 10ft) and high-quality S-Video cable.
Does not make any sense. The video quality should be noticeably better with
the S-Video, but in this case it is the other way around. HOWEVER!! If I use
the ATI-Provided S-Video cable the picture quality is perfect. Problem with
that is that the cable is only 3 feet, which is wayyyy to short for where my
TV is.

Anyone experience this or have any ideas?

The S-Video quality problem mentioned above is quite noticeable with almost
a checkered pattern overlain on the TV. I tried two separate S-Video cables
too. They both did the same thing.

I have a similar problem with a 9800 TV output from Dell. It has diagonal
lines running through all large colored areas.
