So I am not sure if I set something up wrong, but when I try to watch live tv my synology uses a lot of cpu. How do I tell plex to use the transcoded media coming from the HDhomerun extend and not to encode the shows on the fly.
In the PLEX server DVR settings, switch the transcode setting there to use the original file format with no conversion. It may also help to go into the HDHomeRun transcode config settings and uncheck the uncompressed / native signal option there, so only Heavy and Medium are broadcast for use.
After doing the above and making sure the settings were saved, my AppleTV now consistently plays both live TV and recorded shows without any problem over the PLEX app.
I did have to reposition the indoor antenna that’s connected to the HDHomerun EXTEND a couple of times to find the best spot in the room before I had a consistently usable signal across all my channels; even now I’m missing one primetime station and I’ll probably be switching to a roof-mounted one at some point. I do think that helped at least a little, as the HDHomeRun wasn’t struggling to pull in a signal to transcode.
