Help with stabilizing LiveTV via HDHomeRun

[zippy9660]

Jellyfin Version: 10.9.6
Ubuntu Server
Installed via Debian repository

I recently purchased an HDHomeRun FLEX DUO to add Live TV to my Jellyfin server.  Initially this seemed to go ok, but I can't seem to work past a few that just make it feel unstable. 

1. Most notable and frustrating is playback. Initially it will start fine but at some point 2 min or 20 min it will just hang.  No errors that I can find in the jellyfin logs or the ffmpeg logs.  The video just freezes.  This happens on all clients.  Happens more quickly on the Chromecast client, but the web browser client will eventually hang as well.  I can refresh the channel or page and it'll resume playback.
   
2. I occasionally just get a " Playback failed due to a server error. " when trying to choose a channel from the guide.  It does generate the below error, but I never know how to correct it, it just clears up eventually.
   Code:

3. The final issue is the least of my problems, but aesthetically annoys me .  I don't have any preview images.  Seems like it's unable to parse the images downloaded from Schedules Direct?  I cannot for the life of me find that particular error in the log file now.  But I've seen the parse error it get's spammed when it happens.
