Thanks Matt. If by local you mean playing video (mostly MKV's in my case) via a USB stick or hard drive, yes that seems to work fine. Streaming recorded programming on MythTV, network storage or internet streams is where I seem to have trouble. I was originally thinking that I had a network problem but my ROKU/Plex setup on the same network works fine.

plex is transcoding everything down to a lower bitrate, which is likely why you're not seeing any issues. If MythTV is just recording the raw ATSC/DVB/S stream, then it's playing back somewhere around 20Mbps, which shouldn't be an issue, but can be in some environments.

My brother had a similar issue with his Chromebox, even audio streaming would skip from time to time. Doing a full reset on his router and then setting up fresh fixed that, now he can stream 50Mbps bluray ISOs without issue. Something to consider as well.

Again, thanks but that is one of the first things I tried. I expect that my issue is something unique. I'll keep trying different things until this is resolved.
