I have Windows 7 Professional x64, and I recently bought a GT-P6000 TV Tuner card. You need to download both the latest GT-P6000 drivers, as well as the Presto! PVR utility, all from the GIGABYTE website: The drivers are here: GT-P6000 - GIGABYTE - Support&Download - PC Components - Driver The Presto! PVR utility is here: GT-P6000 - GIGABYTE - Support&Download - PC Components - Utility To get Presto! PVR to work, when installing it you have to select the "Run as Administrator" option on the explorer context menu. The picture will then show when the program is run.
