Hi Konstantin, That's an interesting observation, and a valid one given, for example, the addition of QAM-256. I don't know enough about T or T2 to know how the difference impact the tuner requirements. Nevertheless, I can receive the T2 mux that is broadcast in my area. It has to be through my roof antenna, and even when digital switchover is complete here, I doubt that portable antennas will work particularly well here then. If PCTV had the option of using the better tuner, maybe they decided not to because the cost of the Sony demod pushed up the BoM too far already. Impossible to say for sure. I guess we'll have to wait and see if somebody brings out a solution with TDA18272/Sony demod combo before we can compare reception quality.
