[mythtv-users] Tuner freezes after dual DVB-S2 recording

Hi.

I own a TBS 6981 dual tuner DVB-S2 card and I've noticed that when I record
one of the two BBC HD channels along simultaneously with another DVB-S2
channel (either the other BBC HD channel or Channel 4 HD) then the 2nd tuner
freezes and I cannot watch or record tv on this 2nd tuner (comes up with
partial lock or no lock) until I reboot the server.

I notice the cx23885 module is running after it freezes and I cannot seem to
stop it.

I'm running Mythbuntu 0.24/fixes.

This does not happen if I record a BBC HD channel simultaneously with any
other DVB-S channel or on it's own.

The logs are inconclusive (except for the out of frequency range message but
that happens even when the tuner is fine) but here is a section after the
dual recordings finish:
