 >= 2 DVBs :)

Normally the primary card should be configured in a way that it is not
used for recording. Otherwise you can do no viewing and timeshifting. I
have the priority for recordings set to 90. So recording on the primary
will start only when I have selected this or a higher priority
explicitly. The priority for normal recordings defaults to 50 on my
machine.

This would be only possible if you run separate VDRs for each card. But
then you loose the benefit of concurrent recording and/or timeshifting.
For true multi-room support I would use diskless clients with one DVB-s
card using NFS over 100 MBit ethernet.
