Hi Andreas,
do you have two different sat cables running to the two cards or are you using the pass through cable of the rev 1.3 card to feed the sat siggnal to the 2.2 card ?

In the latter case, it is a standar behaviour, since you will be able to tune the second card only to channels that have the same polarity as the channel you are recording on the first card.

If you have indeed two different cables running from your dish, then maybe you have a faulty dual LNB and or problems with the connection.

If you explein how you connected the dish to your two cards it would help to start guessing in the right direction
