I started having trouble with this a couple of weeks ago.
I worked with hauppauge support and got their WinTV product installed and working, but I really don't like this app. I'd prefer to use WMC, however it fails to find the same channels. In fact, it only appears to find the pbs channels. I've tried reinstalling wmc, but it still isn't working. A signal scan shows all channels as weak, except for about 2.
Any ideas as to why I'm able to get this working in WinTV, but not WMC?
