This is mentioned in other places on the internet but thought I would add this here as well. When attempting to stream Netflix movies with my Samsung BD-C6500 Blu-ray Player, I would hear no audio with any movie title, including the Heroes Season 1, Episode 1 that they like to use for troubleshooting purposes for some reason. For reference I am using the latest firmware as of February 7, 2011 (version: BSP-C6500WWB-1020.1 ) with an optical digital cable connection to my Denon AVR-3806 A/V Receiver.
Following advice I found on the net, my current workaround/solution:
Before going into the Netflix application, go into the Pandora radio application and listen to any radio station/channel first. Then, exit Pandora and go into Netflix to watch whatever and the audio will work. I have no idea why it works but it does. It’s either a bug in the player’s firmware or a bug with the Netflix application the player uses. Before you can use Pandora you will need to setup an account with them and then configure the player to use it. The instructions for all this are covered in the manual and Pandora’s site. Using the basic Pandora service is free so no need to worry about any costs associated with it.
Hopefully this will help anyone that runs into a similar issue. 🙂
