I watch streaming video on Netflix, using LG BD670 blu-ray player, connected by optical cable to the receiver Kenwood VR509. The receiver is an older model and does not have HDMI input.
Netflix is streaming many movies with Dolby 5.1 sound. On some of those, the receiver actually switches to Dolby mode; but on the others, it does not. That is, in both cases I select Dolby 5.1 in the options of the movie, but the receiver will detect Dolby in one movie, but only stereo in another.
I called Netflix support; the representative (a supervisor) contacted their technical department and then said that this is known issue, and with optical cable, some movies are known not to be able to transmit 5.1, while some others can. According to him, it's related to some encoding, but he couldn't give more details. "We know about this problem and are working on it; for now, we recommend HDMI connection, then all movies that have Dolby 5.1, will actually play it", he said.
I'm curious, can someone explain how this is possible?
