Audio sync errors after fast forwarding recorded TV

When watching recorded TV, after fast forwarding (skipping commercials for example), The audio channel is out of sync with the video. The video is ahead of the audio by a second. Rewinding the show fixes the issue. Server is a QNAP NAS TVS-673 with 16G of RAM. Clients are Nvidia Shield's. It occurred at 12:56, which should be at the end of the attached log. According to my wife it is an intermittent issue. Thanks, Roger embyserver (2).txt

I'm going to do some testing with the Shield hooked directly into the Tv, and using ARC to the receiver. I've been living with the absolutely obnoxious issue of an audio lag after play/pause condition that is apparently "as designed" by Nvidia with DD signals. Apparently they don't have the license for the DD decoding, and do not implement comfort noise on the output with pass-through and default back to PCM, which introduces the lag to occur. Using the Shield to Tv with ARC seems to remove this
