Drivers for identical hardware MUST be written
to accomodate multiple instances of the device
it's intended for. Very few are.

If the driver assumes it's only going to see one
device, and one device only, it won't work. Video
hardware is particularly picky in this regard as it
interacts with DirectShow and other components
of the OS.

Contact ATI and ask them about multiple identical
devices in the same system. It is possible to have
multiple capture devices (which, at the hardware
level, is what these "tuners" are) IF the mgfr writes
drivers that allow it (I have multiple Winnov capture
cards installed).

I have a Velocity Micro system running Windows Vista Ultimate. I have 4
TV tuners installed. Two of them are ATI DCT (Digital Cable Tuners) that
accomodate cable cards, and the other two are ATI 650 Pro tuners (which
are analog). I ran Media Center set up. The first DCT was recognized and
works correctly. I have tried a million different things and I cannot
get Media Center to recognize the 2nd DCT, or even the two analog
tuners. The error message I get is as follows:
TV SIGNAL CONFIGURATION RESULT
1 tuner detected and configured. Additional tuners were detected but
will not be configured because either they do not have a matching TV
signal or any TV signal at all.
All the tuners have working Cox Cable signals attached to them. All the
tuners are recognized in the device manager and are stated to be working
properly. All the tuners have updated firmware and drivers. The Norton
software was taken off the system to eliminate a firewall issue.
ANY IDEAS?
