No model noted so I'd ask Samsung how to remove the Netflix app (varies with model) so you can get it freshly downloaded. While talking to Samsung, have them check if your model has the latest firmware.
I am watching a show and any time the picture changes a scene it zooms in more. I exit the site go back in and the picture is fine after the Canberra switches to another screen the picture zooms in again. I have no zoom feature on my tv, and i have tried adjusting the audio with no luck.
