Note that the above ActualDevice() returns primary device when transfer
mode is not active, so I guess if the user is for example watching a
recording, this will cause VDR to prefer budget card anyway.

Maybe replace it with cTransferControl::ReceiverDevice(), which returns
NULL when transfer mode is not active?
