Ati problems with XP

Archived from groups: microsoft.public.windowsxp.basics (More info?)

I installed a second graphics card. First one is ATI 8500 AIW. Second card
is Hightech Excalibur Radeon 9200 VIVO.

Both cards work fine, no problems with video or driver installation.
The problem is I cannot play any video. When I try to watch TV it gives me
"TV player failed to initialize the video." The video was working fine with
the 8500 before the 9200 was installed. With Media player, I can hear the
audio, but cannot see the video. With Intervideo's WinDVD it says, "I must
reduce the video size or resolution". All attempts to do this has failed.
I originally installed an NVIDIA pci card and the same thing happened. I was
told through the newsgroups that NVIDIA and ATI do not mix well together. So
I removed the NVIDIA and installed the Radeon card. And this did not work
either.

I really want this to work since the PCI card has dual output and I want to
use a third monitor. This is very frustrating.

Any help would be greatly appreciated.
Thanks, James.
