Bug #3846
Sometimes tvheadend does not want to tune to a channel
0%
Description
There are times when changing channels does work without any problems, but more often than not tvheadend seems to get into a state where it simply refuses to tune to a different channel. The strange thing is that if I subsequently use e.g. Kaffeine to tune to that same channel, Kaffeine is able to do so without problems. Afterwards, tvheadend also wants to tune to that channel again, and also other channels. I doubt signal strength is an issue, because both Kaffeine and tvheadend agree SRN is about 90%.
Log errors are of two kinds:

Tuner is a DVB Sky 950C. Satellite is connected to a rotor system.
I've fiddled with many settings (tune repeats, skip initial bytes, ...) but to no avail...

OK. Do you think that it's a rotor movement issue? Do you see this only when rotor is moved to a new position ?
Anyway, the driver returns a wrong MPEG-TS stream.. So you may also check the mux parameters, if they're correct.

I'm not sure it correlates with rotor movement. I've also reduced the rotor speed setting, so as to be sure the rotation has finished.
I've rescanned all the muxes yesterday. I guess that should have updated them to the correct values? Besides, it's not that a channel consistently fails, it only happens from time to time.
Are there extra debug options that would generate interesting logs?

The problem got successively worse and also occured in Kaffeine in the end. Replacing my tuner card seems to have fixed this problem, so this issue can be closed.
