Step1
First download the ATI Catalyst 7.2 Beta Vista Driver from:
http://downloads.guru3d.com/download.php?det=1577
You will need to install this driver and customize the install to include the T100 drivers.
Step2
After you reboot you will need to update these beta drivers, which includes your catalyst control center. Go to http://ati.amd.com/support/drivers/vista32/common-vista32.html
You should install option 2.
Catalyst Software Suite (32 bit) Multilanguage
and suggested to install the AVIVO package if you can.
Note if the ATI link is changed or updated from above, you can upgrade your catalyst drivers by going to the main ati page and picking your card. Running the newest version of the catalyst should update the drivers in the beta package you installed above. Reboot your computer.
Step3
Download ChrisTV lite (or if you want to support their excellent software one of their other packages) at:

Note I am not affiliated with chris-tv, but I do like the software.
Step4
Reboot your computer.
Step5
You will want to go through the Tuner setup, selecting a combo card setup when prompted.
Step6
You will also want to allow ChrisTV to scan for channels, you can go through their documentation for all available features, but I will help you with one other important feature sound.
Step7
Many AIW cards do not have sound that is sent through the sound card, but instead over the pci-express bus. This being the case with my card you need to go into chris-tv and set this up. Right Click on Chris TV display window and choose program settings.

From the left pane, go down and click on driver settings.
Step9
Click advanced settings tab on the right hand side.
