I was looking forward to watching the footie on TVNZ7 so I grabbed a Hauppauge 900 usb tuner. But when I scan for channels I get everything in really good quality except the TVNZ channels. Gutted. Is there anything I can do to improve my chances? I'm in Auckland central so I didn't expect to have issues with it. I'm using the aerial provided in the apartment block. I'm impressed with the quality of the channels I've got on DVTB, but just seems of waste if I can't see the channels I bought the thing for. Any tips?
