If you have four tuners in the same box, and they are the K-World DVB tuners,
you might want to have a look at your power supply. Those beasts consume a lot
of power. I originally had three in a box and had problems with overheating and
the power supply just not keeping up.
Now since the implementation of DVB multirec I can manage with two tuners,
although I'm considering putting the third in a slave backend one day. I've also
had to beef up the power supply and add extra fans to the box.
The K-World tuners are fine, they just need amps and airflow.
