For further testing I have now modified my cDevice::GetDevice(const cChannel *Channel, int Priority, bool LiveView)
function so that it never returns the primary device. So VDR always runs in
Transfer-Mode, and both the encrypted and the FTA channel will have to
be fetched from my second FF card with CAM (which would then act like
a budget card).

Even in this constellation everything worked as expected, and I was able
to record the encrypted channel and switch live between the FTA and the
encrypted channel.
