You will need to look in /var/log/dmesg for the hardware that
registers on each /dev/dvb device.  Or use the "adapter_nr=" option on
the drivers to lock the hardware to an adapter number, or use udev to
do the same.

Try "grep frontend /var/log/dmesg".

You also seem to have far too few multirec tuners - my recordings
often use at least three on each of the first two of my DVB-T tuners.
The maximum setting is five - I think you should increase yours to at
least three each, and it does not hurt to set it to five unless you
would run out of ability for your disks to cope with that many
recordings at once.
