Description

When Duoflex card's tuners are activated on Digital Devices Cine S2 v6, a tremendous lag is introduced and intermittent stops occur on clients that watch a channel.
TVH GUI gets very slow too. Running on stock Bionic kernel module ddbridge.

OS: Ubuntu Bionic 18.04.1
TVH: 4.3 any version (Currently: 4.3-1506~g77fc1c05f)

By running dmesg | grep DVB, I get a lot of these messages:

ddbridge 0000:03:00.0: DVB: adapter 7 frontend 0 frequency 0 out of range (950000..2150000)
