This has been reported and is currently with the Plex Media Server development team to address. See this post which refers to duplicates issues that are being addressed in Plex Media Server and Plex Web EPG issues since the new update to Plex server. Channel Matching not matching the guide - #149 by sa2000
This appears to be different from the two issues that I mentioned that are already being addressed
In this case - the tuner is giving two channels with the same number ? 7.1 ? I am not sure how we would be able to tune to the right channel when communicating with the tuner.
Could you provide me with debug server logs covering the time when the DVR is setup and channel matching occurs. I would like to see what requests we would be sending the tuner to list the channels - so that you can do that manually and let me see what the response contains
Also - is this OTA through Antenna ? Is it DVB-T / DVB-T2 ? What is the DVR make and model ? Networked or PCI / USB ?
Also let me have country / zip code / and the lineup/guide name selected
