OK, gave it a whirl and had no conflicts with any video drivers. The 2 error messages I ger are: (1) Windows Media Center receiver service stopped working and was closed. (2) A problem caused the application to stop working correctly. Windows will notify you if a solution is available. These messages come up whenever I try to use the media center in VISTA. I have a call in with Hauppague to see if they have any idea since I am using one of their tuners.
