Recent purchase and set up. All is working good, remote controls TV, Sound Bar and online connections no problem. For the first time tried playing a Blu Ray DVD, once inserted the screen notes Blu Ray Disk for a second but then jumps to what ever last was shown on the web service. Using Function key I can eject the Disk, but do not know how to choose DVD player over Cable box. I would guess its a simple configuration that I haven't found or a remote control combined key stroke to get the DVD out put on the screen, any suggestions appreciated.
