Now I followed the Cranznz guide and initial steps went without a hitch. In TV server I can actually preview all the channels in a small window using FFWD show.
But when I go to step 2 to Congifure MediaPortal I get windows has reported a problem. I uninstalled and reinstalled a couple of times and same issue - not once been able to launch Media Portal itself.
Given I can actual see the TV working albeit in a small window - I wonder is it something simple?
Failing that - what else can I watch Freeview in instead of MP ie how can I make the FFS window bigger?
Does the Hauppauge software actually work just for viewing...might try that now.
