I am having problems viewing Live TV on my iPhone. Plex loads the channel however after a few seconds it starts buffering and will only play a few seconds of live TV before starting buffering again. My Plex Media Server is setup on a QNAP TS-451 NAS with 8 GB of ram and I am using an HDHomerun Extend. Hopefully, it is just a setting that I am missing, but after a few minutes on trying to view TV from my phone my NAS is out of RAM.
Is your NAS a 451 or 451+?
