Duplicate channel mapping error for two different channels

Server Version#: 4.39.1
Player Version#: all
Tuner Make/Model: HDHomeRun PRIME
Guide/Lineup name: Spectrum Leicester Digital
Using XMLTV?: Default
Channel number/Name: Multiple

My tuners were missing a couple channels so I re-ran a channel scan. I then went into the settings and told Plex what channels they corresponded to. But when I try to save it says, for example, “There is a duplicate channel mapping (Channels 315, 38 are mapped to Guide channel 315)”

Channels 315 and 38 are the same channel, sort of - Golf and Golf HD. But the mappings are different. One is mapped to “038 GOLF (The Golf Channel)” and one is mapped to “315 GOLF (The Golf Channel)”. If I uncheck channel 38 the issue goes away for that channel but then pops up for another set of channels following the same scenario (e.g., a non HD and HD version of the same channel are mapped to guide channel XXX). How can I fix this without removing every single SD channel source from my lineup?

I do see a lot of duplicated channels on the Spectrum cable lineup. In fact they also show duplicate channels on their list of channels https://www.spectrum.com/browse/content/new-channel-lineup
(but for some reason Golf is showing there as 38 and 768 and not 315)

In their list the duplicate channels appear the same and not SD and HD - but both showing as identical channels

Do you have any evidence that they are SD and HD - if they are, then lineup would need to have them as separate source channels internally and so not end up with duplicate

We cannot handle a channel appearing on more than one number

These are few examples of the duplicates

Do you actually receive all the duplicates ? And can you tell if they should be SD and HD ?

For now you would need to do what you have done - disable the duplicates leaving only one

So it’s anecdotal because I haven’t checked every channel but yes, the two digit channels are usually SD and the three digit ones are HD. I just fired up the HDHomeRun app and am watching Golf SD on channel 38 right now.

The thing is, when choosing the channel information it does show a different number for SD vs HD, which one would think means that Plex realizes that they are different distinct channels. See below:

I stopped trying to fix the duplicates after around item 20 because it got tedious. There’s really no other way to fix this? I guess I can try mass un-checking the lower channels or something.

My guess is that the information our provider had for the channels did not distinguish between SD and HD for some channels - in fact the Spectrun web site does not

I will need to refer this to our provider to get the SD / HD channels separated into different titles. Some appear to have already been done eg CNBC and CNN - which show the same here


but are actually split into separate channel names in the guide data

It does not appear to follow that 2 digits is SD - because i see that this channel is showing as HD

I am attaching all the duplicates - are you in a position to identify SD / HD ?

I have submitted to our provider the list of duplicates on the following lineups to look into as priority and then check other Spectrum lineups

Spectrum Long Beach Digital
Spectrum Livonia Digital
Spectrum Leicester Digital
