Live TV stream cuts out

Here is my setup - PMS on Nvidia shield, HDHomerun Quatro, Roku 3. All hard wired (no wireless). When I am watching live tv after a while the channel will drop out and the plex client on the roku will appear to try to reconnect to the stream and will hang at 36%. If I back out to the guide and go back into the channel, it starts playing again. I updated the Plex client on the Roku last night when I saw that there were some live tv fixes. Any thoughts?

I am getting a lot of buffering with my roku watching live tv too. All my stuff is hardwired. It is driving my nuts trying to watch the Stanley Cup.
