This is a very bad advice.

Due to how myth is handling the creation of recorder; doing like you
describe will break the multirec functionality.

You do *not* want to set it to a max recordings of 1; and then later
change it to something else.

If you change the number of max recordings, you should first delete
the card, and then re-add it. By doing so however, the number sequence
of recorders won't be continuous.

If you want it to be continuous: 1,2,3,....n then you must delete all
capture cards and re-add them all one at a time'

this is very inconvenient.

Again, this serves no purpose for digital TV capture card.
You can't use as device name in mythtv-setup anything but something
with the path : /dev/dvb/adaptorN

Don't see much the point of having the tuners in a specific order, as
all things being equal which one is going to use is irrelevant.
