I've been streaming Netflix through my Samsung plasma for several months beautifully. Have been pleasantly surprised that it passes 5.1 info to the receiver. As of yesterday I get no audio at all to pass from the optical output on the TV to the Denon receiver with the Netflix app. All other apps - Pandora, Youtube etc, and the sound made by the TV itself play just fine. When streaming through my Sony Blu-Ray player I do get sound, so I don't think it's a Netflix issue. But the Sony doesn't pass surround signals and has trouble maintaining a wifi connection, so I don't really want to use it. Has anybody else had an issue with the Samsung Netflix app?
