I would like to add another issue that is related to this: If you have a
VDR with more than one card, and you do not have connected a cable to
all cards, VDR should try to record on a different card if it can not
tune to the card it selected for recording first. I come into this
situation because I sometimes use my VDR at a location where only one
SAT cable is available.

Wolfgang
