If cards 1 and 3 are for Astra you have to set the Ca field to 5 and for
Hotbird to 2. The "b" was just a comment.

indexmask contains the value you have provided in the ca field. If the
ca field is zero (all cards) the value is set to all one's.
The code then checks whether the bit for the currently tested card is
set.

This code is just a quick hack I have done to select specific cards as
you want to do. You have to edit the channels.conf file to set the
parameter. It is not possible to set it with the channels menu in VDR. I
hope Klaus will add a similar feature in the future because it allows a
very flexible use of the cards.
