Hope possum girl can answer this. Have all Sammy units,3d tv series 7150, Sammy sound bar hwe450'c,and Sammy blue bdem59. Same issue want all sound thru bar. Current hookup All hdmi cables, cable box out to bar in,, bar out to tv arc, blue ray out to hdmi tv 3 Same problems as others. Currently tv plays great thru bar but blue ray only plays thru tv speakers. With bar selected to hdmi source still can hear tv over top of DVD player. I must shut off bar to here blue. Ok possum girl don't fail me now DR D I am not worried about on off issues and using multi remotes. Still confused with any net but don't think it means anything. Also my Cecil is turned on the tv.
