Enabled the code which sets the consumer run-mode based

on the current play back mode. I.e. paused or stopped
playback get's B_OFFLINE run-mode, which makes sure the
Consumer does not drop frames when they are too late.
When single stepping frames backwards, the producer may
have needed a lot of time to generate a frame and it may
arrive late, which is no problem when the video is paused.
