If there is more than one DVB card, VDR does NOT use the primary card
for EPG scanning. The "emergency exit" due to a sequence of failed
channel switchings is ONLY done if those switchings are done on the
PRIMARY DVB card. Hence the EPG scan will NOT interrupt an ongoing recording.
At least that's the way it was meant to be...
