Tuner 1 is for the program you are watching
Tuners 2 and 3 only show a signal when you are recording something, or the VoD is updating
Tuner 4 is for the iPlate, etc
You really need a sat meter for (1), but..
1 Check the dish alignment
2 Check the skew angle. It should be 153 deg (about 4.30 pm)
The skew angle is the one that commands the least attention, but can affect recordings, etc
Lastly, what is the condition of the cable from the LNB to the receiver? If it is over 5 years old, best replace it. Also make sure that the connections to the LNB are clean (spotless) and sealed with self-amalgamating tape.
