Yes.

Why is 6 better when it is used and 7 (other card/other cable-box/same
channels) is free? I've read a lot but that's very hard for me.

I use priorities only for 4 fta channel on the Satelco DVB-C card. When
I add this card to the bottom, live-tv is started with those 4 channels
and I want these only for some recordings.

I don't know what you mean with "get another PVR-150 that can be
dedicated to the satellite set-top box"
I've got 2 PVR's and two boxes. Box1 to PVR (/dev/video0)  and Box2 to
PVR (/dev/video1).

It are the same cable-boxes, (Thomson from UPC - The Netherlands - sorry
for my poor English ;-).

It's not clear for me why this happens. Before I had the boxes connected
I used the Tuner feature of the card for analog tv, and this never happens.
