#8251 closed Patch - Bug Fix (fixed)
EIT Scanner disregards input groups, causes undefined behavior

Description
Hybrid tuners analog and digital sides share a tuner, and thus are properly configured as members of the same input group. The EIT scanner disregards input groups and will kick off when the analog side is in use, putting the hardware in an undefined state and causing tuning failures and other potential Bad Things (tm), which will vary by driver.
The EIT scanner should account for the other members of the input group.

I think my installation runs into this problem each day - I will take a closer look the next days.

I've downgraded this from critical to minor. It doesn't affect many people and the workaround is simply not to enable eit scanning on any dtv recorder also used for it's analog side.
I've attached a patch which should automatically disable active EIT scanning when an input is shared with an analog recorder. It is untested, but should provide a good start for anyone working on this. The main concern is that it has a bad effect on a DVB-S card with DiSEqC inputs. Since this does need a testing both for function and for no ill-effect on DiSEqC setups I'm moving the milestone to 0.26, but if this receives sufficient testing there is no reason it can't be put in for 0.25.

I have two virtual encoders configured for my DVB-S2 card and see the same behaviour.
I have attached a modified patch which delays the EIT-Scan for 60 seconds if another card in the same input group is busy. It works for me!

Reschedule all tickets planned for, but not solved in time for, 0.27.6 to 0.27.7.

I'm bumping the priority but moving this to 0.25 since no-one with an interest in this area of the code has the time to work on a fix for 0.24. This is clearly a serious bug all the same.
