Does anyone know if new televisions this year already have the MPEG-4 tuners in rather than MPEG-2? I'm a little confused having read about future updates to the freeview service, with possibly HD channels available via Freeview. If the new teles being sold in shops now don't have the MPEG-4 tuners in does that mean that the freeview tuner in a modern TV will simply cease to work when digital swithcover is complete?
