I found the product support option for the application and driver download greyed out. This is why I suspect the only actual support you will see is through Sony. The model is listed but manufactured not for direct sale but as addon for Sony laptops. You run into that quite a bit.
The tuner card here was ordered separately through newegg and still sees updates available at the manufacturer's site since they sold the A180 generally not just through any OEM manufacturer. While the application may appear differently for the Sony version you would still have to look through the setup proceedures to some extent.
There have been a few occasions here on XP and Vista as well as 7 where you simply had to fight to get the tuner driver to work and then see the composite input used here. Reinstall a few times, reboot a few, and finally the picture.
As far as switching from Ultimate downward to Pro you may have been better off staying with the Ultimate edition when you had everything working if you were able to. Here I use the card for viewing and planned captures started manually. That could be from a camcorder as well as anything being viewed live.
You're now running into what I have already seen a few times only with a different type and model card. It can be a royal pain at times! One thing never to do with any of these cards is apply an MS update version of the driver once you have everything set. The driver isn't any newer but will trash a working install forcing you reinstall both driver and app of the exact same version all over again!
been there, done that a few times!
