There are two different issues. Let's tackle one at a time.
Netflix streaming is seperate from DLNA. When you say you're having trouble with the Netflix, what specific streaming issues are you having?
DLNA has a list of approved audio codecs in the manual for each specific series of televisions, and the resolution, codec and audio codec all have to match up.
Keep me posted.
Hello. I have Samsung UN55B7100 and UN40B7000 and both are having problems with codecs in playing either streamed movies from the using PC Share software, or from Netflix using an internet connected Samsung Blu-Ray player. It does play some movies. Other it would say the codec is not available and then goes to the next movie until it finds one that works. Yet, sometimes it would play the video without sound, with the error message that a suitable audio codec was not found to play the sound. I've basically tried installing all the available codecs on my PC, but that did not solve the problem. How goes one solve this issue. Thank you.
