SVN 11230

I am getting recording conflicts even if I have two idle TV-Cards. (See screenshot below).
DMAX is only available via cable, ARD is available for all cards. These two shown recordings are the only ones at that time.
My guess is that MP tries to use Analog-Card for ARD-Recording (which is already in use by DMAX-Recording). Tried to set up Card-Priorities (Analog higher, DVB-T lower and vice versa), but didnt change the problem.
