I have a Mini Vox connected via MoCA to a Premier 4. Occasionally (once a month(ish)) the audio on the TV attached to the Mini will become choppy for no apparent reason. The video will still be smooth but Live TV and any recordings I play have the same choppy audio issue. I can watch Live TV or recordings on the premier at the same time with no problem. I've tried rebooting both boxes and it doesn't fix it. Also changing the channel does nothing. Every channel and recording has this problem. Eventually it works itself out and the audio becomes smooth again. I can change the audio output on the Vox from Dolby to PCM and it helps, but you can still tell there is a stutter. Has anyone else had an issue like this?
