Below are steps that may solve the rebuffering issue.
I tried this. The LOGIC: There may be some programs in the SmartHub that are affecting Netflix & more. By doing this RESET, it gets rid of the offending programs upon restart.
When I did this procedure, I still had an issue, but the more I used Netflix the less rebuffering. Finally I am now able to watch entire programs without a hiccup.
BUT, ocassionally it STILL hangs when first getting on Netflix. Then I must power down, but then it works OK again.
ALSO, if you are getting flutter on some BluRays, then you need to UNPLUG your unit for 60sec and then go back to your disc.
This IS a hassle, but for now it is a work around. SAMSUNG DOES NOT ACKNOWLEDGE THAT THEY HAVE A PROBLEM. This is their solution to YOUR problem.
Good luck, Classico
HERE ARE THE STEPS THAT WORKED FOR ME--AS FAR AS IT GOES
Perform the steps mentioned below to reset the player:
Shane: 1) With no disc in the player press and hold the Stop button on the front of your Blu-ray player for about 8 seconds or until the front display reads SETUP'. 'Resetting all settings to default values is displayed on your TV screen as the Blu-ray player powers off and resets.
Shane: 2) The Blu-ray player is automatically powered on after the reset and the select Language screen is displayed.
Shane: 3) Please ensure no disc inside the player and disc tray should be open while holding 'Stop' button.
