I bought the samen tv and do have the same problems. The sound isn't in sync with the video, because the TV is fixing the video which takes some time. I also use a seperate home cinema. I have read that devices can have lip sync which helps them to communicate together, bus my AV doesn't have it. Therefore, the only thing you can do is adjusting the AV (Sound), not the video, because de screen is always slower because of the adjustments. I turned of things like pixel aprovement, etc. This helps to sync the sound. You could have a look if your AV (sound) has could be delayed, but you need to adjust it all the time.

Do you know how to post new topics in here, because I've managed to stream almost everything. The only thing which doesn't fully stream is "dolby digital", PCM works fine!

Kind regards,
