Just setup TV service on Windows Media Server now MP TV service broken (1 Viewer)

[itm]

I decided to try out the TV service with Windows Media Center (on Windows 7 Ultimate SP1), and set up the tuner for it. Now MediaPortal can't seem to receive a TV signal. Can MediaPortal not co-exist with WMC? If not, what do I need to do to re-assign the TV tuner to MP? (it's a Blackgold DVBT2 card)

...I get an "unknown error" when I select a channel from the TV Guide. After a reboot I now find that WMC can't access the TV tuner either - it says that another application is using it
