Is vdr able to get the EPG-Data from the watching-DVB-card? (View/Record channel + get EPG-data)
Then it is not needed for the EPG scanner to tune in this frequency, and thus the 2 cards don't tune in the same frequency.
This way recording/viewing/epg-data-fetch is always done with one card, other frequencies with the other card(s) ==> no more inteferences!
