If the 4 cards/sticks are all the same model/class and receive a good
signal, it shouldn't matter if devices move around at boot (i.e. if
/dev/dvb/adaptor0/ becomes /dev/dvb/adaptor2/).
Inconsistent device numbering causes problems is when a user has
different classes of device (i.e. DVB-T and DVB-S devices using the
/dev/dvb/* tree, or analogue and hardware encoding capture cards using
/dev/videoX devices), or when different cards receive different signal
strengths, and you want the ability to prefer particular cards over
others.
udev rules specifying PCI addresses (which should be consistent)
should be able to better differentiate between multiple identical
cards if specific card numbering is required.
