im confused, ive finally just hooked up my cable connection to this damn unit, it was fine in my vu duo2, solid signal. this box, ive tried 3 different images, but even on bbc1 the signal pixelates bad, i.e unwatchable - but signal says 85% - no fluctation in the signal number...

anything else i can try before i return it, based on a suspect faulty tuner?
