Hi Marc,
you've lost me.
If FE0/0 is a DDBridge tuner, and I make the FF card tuner
FE0/0, then I still need to rename the DDBridge Tuner that
was FE0/0 to another one within FE{1-3}/0. That means
potentially overwriting the names of some of the other
DDBridge
tuners, and then renaming them later on too.
Unfortunately the same rule will pop for all four DDBridge
tuners, so I guess I must keep track of what I have already
renamed.
That's what the external program is intended for. It will be
launched for every tuner of the ddbridge. The example I give is
basic, if the node of the first front end isn't already created,
then echo the name of the first front end. If not, test the second
node and do the same thing for all the 4 fronts end. Maybe you can
use a better logic by passing some parameters.
Of course, this is possible only if the tuners of the ddbridge
keep the same order but if would be weird if the driver doesn't
use the same order every time (no module loading order at this
level).
You still need a rule for the FF card because there are more node
created for each adapter. Without a rule the number of this card
could change too despite the rule for the ddbridge.
To avoid overwriting when a new tuner (without a udev rule) is
added, perhaps you can start numbering at 10 or more if vdr can
handle it.
Or, hows about I just go in and rename the devices, same scheme
every time. I think that would work if I knew
how to differentiate between the 4 Cine S2 tuners, currently I
dont know how to do that.
That's a more standard way but according to the output of udevadm,
there is only an empty DRIVER field after the ddbridge, nothing to
write the rule witch differentiate the tuners.

One more thing. Meanwhile, you can use the solution of blacklisting
the dvb modules and manually load them before starting vdr. This
solution should works but is not very stable: the modules name could
change from time to time and you have to take care to not start vdr
before all the front end are fully initialized.
Marc.
