Today I bought a HDR-FOX T2 to replace my PVR9300T, but quickly found a problem: No HD channels were tuned in by the set-up wizard. The HDTV Group is empty. At the same time the TV's internal tuner, still connected via Antenna Out, receives an excellent strong HD signal. (Crystal Palace transmitter is about 5km away and we had good roof-top aerial installed when the PVR was purchased in 2009). How can I get the HDR to tune the HD channels?
