Sorry if it was a bit unclear; my situation is with only one TV-card, an analog one. So there is no priority setting.

You say the option for not merging channels is only available for your analog card? If merging is only for analog cards, then I don't understand the reason for having merging as the default at all. Or are there analog setups that don't have the problems I am having?

I understand the possibility to change the merging option. My problem is with the default; it should be to NOT merge analog channels. And of course exported/imported channel setups should not be merged...
