Driver Issue With TV Tuner Card

PlusTV HD PCI 120 TV tuner / Video Capture Card

Hello
I recently bought a PlusTV HD PCI 120 video card, (Model VS-ATSC120)
I am running WINDOWS VISTA HOME PREMIUM.

The instructions say to install the drivers from the disc, and do not let
WINDOWS update find, and install them.
In Advance System Settings, I checked the box to "Never check for drivers
when I install a device"

I then try to install the driver from the disc that came with the video
card, but WINDOWS automatically locates a driver, and installs it for the
"PCI ATSC Hybrid DTV Device"
I assume that is the TV tuner, which does not work. When I connect the cable
source, no signals are found.

However, when I connect a Video Source, the PCI Hybrid Video Device works
fine. (With drivers WINDOWS installed, not from the disc, since WINDOWS won't
let me load drivers from the disc.

When I go to Device Manager, Sound and Video Game Controllers, PCI ATSC
Hybrid DTV Device, and click properties, it says "No drivers are installed
for this device".
However when I click driver, it says "Driver Version 5.8.413.0"

I've done repeated uninstalls of this device, and restarts, to no avail.
WINDOWS still locates a driver that doesn't work, even though I have the
"Never check for drivers when I install a device" check box checked.

What I have in the end, is a card that works fine for Video, but NO TV
TUNER, which is what I wanted.

Can anyone help me with a work around for this issue, such that I can use
the TV tuner on this card?

(I'm sure I would have no problems if I were running XP)

Thank you for any help you can provide.
