I have done quite a bit of searching for the solution to this, so please excuse me if I have missed the answer!
I have just bought a second hand hdr-fox t2, which is replacing my old trusty pvr-9150t.
When I set it up, it auto tuned and gave me a selection of channels but no HD, when I looked at the tuning channels , it was selecting a different transmitter than the 9150t had done, along with a tv upstairs that id also manually retuned.
I tried a factory reset and cancelled the auto installing, saving no channels, then adding them manually, but it just says no channels found for all the ones in my area. I got my info for manual tuning off the official freeview site.
When it auto tunes, and doesn't select the winter hill transmitter, it means I can't use the hd channels, as they just break up.
I plugged the 9150t back in and it's up and running straight away with the winter hill channels.
Any suggestions greatfully received.
Thanks in advance
Clarkee.
