In setup.conf there is a variable:
vdr:~# grep Prim /var/lib/vdr/setup.conf
PrimaryDVB = 1
PrimaryLimit = 0
(PrimaryLimit seems to have no sense anymore?)
What's the problem of a "string" there:
PrimaryDVB = /dev/dvb/myprimarycard/
Currently there is stored where the last time the first FF card was found,
what is not allways working good
vdr:~# dmesg | grep frontend
DVB: registering frontend 0 (Zarlink MT352 DVB-T)...
DVB: registering frontend 1 (ST STV0299 DVB-S)...
DVB: registering frontend 2 (ST STV0299 DVB-S)...
DVB: registering frontend 3 (ST STV0299 DVB-S)...
will lead to "PrimaryDVB = 2"
After fidling arround i could manage (somettimes) to get:
vdr:~# dmesg | grep frontend
DVB: registering frontend 0 (ST STV0299 DVB-S)...
DVB: registering frontend 1 (ST STV0299 DVB-S)...
DVB: registering frontend 2 (ST STV0299 DVB-S)...
DVB: registering frontend 3 (Zarlink MT352 DVB-T)...
Wow! but the box does not work anymore...no video, no audio, no OSD.
PrimaryDVB = 2
now points to "frontend 1" where no TV/Sound hardware is connected.
So this "automatic" does not really work, and makes configuration
more complicate. (If *i* said: use "PrimaryDVB = 2", the box must do.
If this is wrong, VDR could/should issue a warning, but not change
the recommended PrimaryDVB.
It would be easier if there could be a symlink be used instead/addition
to the single digit.
Remember the history:
This "PrimaryDVB = 2" stems from a time, when there were only
badly working FF cards (with severe(!)hardware bugs).
No budgets, no DVB-T to be mixed because not supported or not existing!
A card found at slot1 stays at the index...
But today?
With udev?
Why not use both? (to be compatible)
If 1 or 2 Digits than old
else take as device path.
