I don't believe this is related to the new F/W, I believe it was occurring before that. I'm getting audio dropouts that last less than one second on playback. It doesn't appear to be any specific channel. I'm OTA only. I don't see a pattern to it. The video is solid. Audio is thru a HDMI cable. I haven't tried a separate optical cable. Watching the display on my Yamaha A/V receiver, it shows the loss of the audio stream. I have a 2nd deck, but it is only connected to a small receiver by analog cables.
