Just to add an information footnote to this thread.

If you have different tuner card types in your backend you can find
that sometimes they will load in the Kernel in a different order, this
is down to how fast a card starts up and signals it's availability in
either a warm or cold reboot.

Therefore if you have a mix of physical card types it's wise to
blacklist them all loading on boot and write a script that loads them
in a specific order with sleep commands between each card load
command, this will avoid you for example trying to record DVB-T
recordings in your DVB-S card that loaded quicker this boot.
