you have dvb-s and dvb-s2 channels in your db. when you now go to the map channels section and try to map channels to a dvb-s card, then all dvb-s2 channels are hidden from the channellist (so far so good).

Configuration will then display a popup window, which explains to the user that channels are not displayed since the card he maps channels to is dvb-s and not dvb-s2.
The problem now is that a popup for every channel is displayed.
So if you have 40 dvb-s2 channels which can not be mapped, then you get 40 popups.

This has to be changed to one popup, telling the user that X channels are not displayed in the list because they are dvb-s2 and the card he maps channels to is dvb-s.
