That's maybe the current limiter of the LNB-Chip if
you wire too cards together without a multiswitch...?

Did you try if EPGtimeout=0 solves the problem?
(EPG uses the unused card to get the EPG of the other channels.
That of cause leds to unexpected v/h switches if you
have only one cable. If recording "h": No problem, but "v" will
be over ridden by "h" )
