As to the satellite tuners.
In my local store there are single and twin tuner options - two single tuners or one twin tuner and an empty slot for a possible dvb-c tuner, etc.
The question is: in practical terms, is the single tuner of Vu+ Duo2 much better than the twin tuner or pretty much the same?
The overall sensitivity, the absence of holes/problems with some particular frequencies/transponders, the output signal quality.
I feel instinctively that a single tuner should be better than a twin tuner, but perhaps there are no noticeable differences?
