Hello, I have such a problem that I set the antenna with an ordinary satfinder the best I can and catch the signal on Cyfrowy Polsat 66% and quality 83% according to the PVR HD 7000 decoder / tuner on the Polsat hd channel. When I change the channel on tvp 2 hd or eurosport 2 hd and take on the indication of the power and quality of the signal on these channels, the value is 0%. These channels do not work at all and a message about no antenna signal is displayed! What is going on ? Tvp 1 hd works and Eurosport hd works too. I think that since I have the quality of the signal strength on other channels, then it should be something that also appears on this and here is nothing to see if it can be a problem? The tuner is the one that connects to it and internet is also connected to it. 80cm canopy.
