I just bought this TV tuner for my MacBook Pro today. I'm in the centre of London and get no digital channels at all no matter how I much I tune and search. Freeview says I should get all channels in this area. So I took the TV tuner to the Apple Store on Regent Street and got the same results there. Nothing, not one channel, yet this is supposed to be a great TV tuner and I'm in an area with full coverage. I have tried connecting to the roof antenna and the two wireless antennas, and in all configurations.
I also did an exchange at Apple Store. Still no result. Any tips or known problems I should know about please?
