MediaPortal thinks I don't have an installed TV tuner card (1 Viewer)

[STEVENJ]

I've run the configuration utilities and specified my Hauppage WinTV HVR-1250 as the TV tuner card and I've indicated that it's a hybrid (NTSC analogue/ATSC digital) card. At some point the configuration utility had it scan for channels (which it did successfully). However, when I run MediaPortal 1.0.2.0 it can't find any TV tuner card.
