I have an old ATI PCI 650 tuner and I started to lose some channels. I am connected to Cablevision and was using the tuner to view and record TV programs using a clear QAM signal. I noticed that the number of channels has dropped to nine. I lost WCBS-DT and WNBC-TV. I am running Windows 7 64 bit Ultimate and have SP1 installed and have the ATI WDM 10.4 installed for the tuner, which is the latest version. I downloaded and re-installed the driver. The cable package is the least expensive from Cablevision. The other TVs in the household can pick up the signals rom the connection I had the computer connected to. Thank you.
