I just finished installing Mediaportal on a new build PC. The PC will only be used to record TV when I am not at home so I can view it later. I get my TV signal from an antenna on my roof. I am running Windows 7. I cannot get Mediaportal to map my TV signal. It shows now channels. When I click map using the AverMeida dual TV tuner in my computer nothing happens. It shows the tuner in the map window. I click OK and it closes the window but does not map the channels for my TV. What am I doing wrong. The driver for the TV tuner card says it is working properly. Mediaportal seem to see the tuner because it is an option in the map channel window. Can anyone help me?
