Windows 8 Release Preview: I was not successful in persuading my TV receiver http://leadtek.com/eng/multimedia/overview.asp?lineid=6&pronameid=458&check=f to work, although I used W7 drivers and Winfast PVR2 is officially compatible with W7. All I get is error message ("Fails to build graph") when I try to launch Winfast PVR2 application. The tuner performs well in W7 Media Center. Different error message appears when I try to manually put the drivers in place. http://andrewz1986.blogspot.cz/2012/06/betatesting-windows-8-release-preview.html
