When streaming video's from my pc to my home theater system the audio cuts out, the video plays fine. If i turn the receiver off the audio plays fine on the tv speakers, but when going through the receiver it cuts outs and the receivers screen will actually blink. The receiver is connected to the TV via optical spdif. Audio from HDMI streams just fine from the tv to the receiver, its just with some videos across DNLA. Issue is with most of my .mkv, .mp4 and even some .avi files. Tv is a Samsung Un46C6300 and receiver is a Samsung hw-700b. I have tried 2 different spdif cables that both work fine on other equipment.
