Hi Rgann -
It looks like the VI mentioned has been taken down in the five years since it was posted. NI doesn't provide any LabVIEW drivers for third-party devices, and I'm unable to find any currently on the DevZone. I recommend contacting Hauppauge for more information. They may at least be able to provide you with a driver API that can be called from LabVIEW.
Of course, there's always the hope that one of our forum regulars has some code you can use, too!
