OK, I've found the solution! After fiddling around with the driver file that I got from
here forever, I went back and looked through the site some more. After a while, I found the Vista Hardware Installer
here.
After that, I installed the file, restarted the computer and then plugged the DVC 170 in (which had been unplugged and uninstalled through the whole thing). After the device finished installing, I checked device manager and it showed that the new drivers were installed. When I started Studio 10 and changed the capture source to the DVC 170 and my computer did
not crash.
