Missing substations for station in Plex Channel Scan

Server Version#: 1.42.2.10156
Player Version#:
Tuner Make/Model: hauppauge wintv-quadhd
Guide/Lineup name:
Using XMLTV?:
Channel number/Name: 26.1 to 26.8

In Plex tuner setup under Scanned Channels /EPG Guide Channels 26.1 to 26.8 are not showing up only 26.9 to 26.14 see attached picture:

But in Live TV Guide 26.1 to 26.10 show up with incorrect guide listings:

Wondering if this is possible a bug since 26 has so many subchannels. The problem is since they don’t show up in tuner guide you can’t edit the epg settings and the remaining channels don’t show up in the live listings even though they are selected. Is this a bug with the new version or am I possibly doing something incorrectly?

There is a separate category for Live TV EPG data issues.

Thanks added it but left it here as the channels are not showing in the list after tuner scan

Hi,

I need to know your postal code to report missing channel EPG. Often low power stations (usually sub-channels) Gracenote will not get EPG for.

Zip is 67031 but even without the guide shouldn’t it show the channel in the tuner list after a scan so you can map it?

If channels are not showing up in the left side static column then the tuner is not picking them up or too weak of a signal to use.

You may need to move the antenna to another location or get a signal booster. Another user recently was not getting some channels but did on when plugged directly into their TV. It turned out their signal booster was not working and they had to get a new one. They showed when antenna attached directly to TV because they were bypassing booster.

But the channel that doesn’t show on tuner setup is in the guide and is watchable with plenty of signal. The ones that are showing in the tuner match up screen don’t show in guide.

The Plex Tuner in the Live TV & DVR sees the Hauppauge WinTV-QuadHD as two devices - each a WinTV-DualHD. You have to scan both to use all 4 tuners. You’ve shown us one of the two devices. Show us the scan from the other device.

Well, you’re right. This doesn’t make any sense. Channel 26.1 Cozi doesn’t show up in the tuner scans, but does show up in the Live TV Guide. Crazy.
When you watch channel 26.1 Cozi, do you actually get the Cozi channel and the programming that is listed in the guide?
If not, what is actually showing up on the channel? Is it another station that you can find in the guide?

Actually 26.1, 26.2, 26.3, 26.4, 26.5, 26.6, 26.7, 26.8, 26.9 and 26.10 don’t show in the tuner selection but do show up in the guide. 26.11 to 26.14 show up on the tuner selection but don’t show up in the guide. 26.1 to 26.10 have the wrong EPG data but since they don’t show up in tuner selection they don’t seem to be able to be corrected.

@dpie30 The EPG data that you get through Plex actually comes from Gracenote. Gracenote creates the EPG data from the data that they get from the TV stations. Your channel 26 KAGW seems to be changing the channel line-up fairly regularly. It doesn’t look like Gracenote is keeping up with the changes. A Plex Team Member might be able to help get it sorted out, but I’ve had better luck just contacting the TV station and explaining how I get my EPG data and what issues I’m seeing with their TV schedule. Also, I use TitanTV as a source to check the TV schedule against what I see from Gracenote.
A bigger issue is the fact that your Tuner scan doesn’t agree with the TV channel line-up. If this was a Plex bug, I would expect a lot of Plex users up in arms over the TV channel line-up not matching the scan. I suspect that it has more to do with something gone awry with your database. I would do the following:
Stop plexmediaserver
Get into the Databases directory:

plex@plexmediaserver:/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases$  

There are 3 TV EPG database files:

tv.plex.providers.epg.cloud-93e4c08c-efdb-4012-aa22-00e923a8ddf4.db
tv.plex.providers.epg.cloud-93e4c08c-efdb-4012-aa22-00e923a8ddf4.db-shm
tv.plex.providers.epg.cloud-93e4c08c-efdb-4012-aa22-00e923a8ddf4.db-wal

Rename each by adding .bak to the end of the filenames,
Reboot the server.
Plex should re-populate the database with new files.

What shows in the Guide on the left of the channel logo should be the channel from the EPG. Like if 35.1 epg was selected/mapped for tuner channel 99.2 then 35.1 is what will show in the guide even though what is actually playing is 99.2

but i am guessing you are saying there is no channel ( in the entire list) mapped to 26.1 which i am not sure how can be. unless there is stale EPG data

deleted tuners and these files and still only see 16.9 to 16.14 in tuner selection. I may try with another server.

I’d be very interested to know what channel is actually showing up on your 26.1 Cozi. That might be a clue into what is going on. You could use Titan TV to compare the tv schedule to what you’re seeing.

One other thing to note. In your tuner channel scan the channels listed on the left side are identified from the data (PSIP) that is embedded into the broadcast signal, in the same way that a simple Mediasonic ATSC tuner can find the channel numbers from the signal. Since your system is only picking up 26.9 thru 26.14 in the scan, you are missing 26.1 thru 26.8 for some reason. I don’t expect that this is a Plex issue. Your channel 26 actually broadcasts on RF channels 24.3 thru 24.16. I have a station in my area that also broadcasts on RF channels 24.3 thru 24.13. Plex can pick up all these channels and accurately recognize them as Display Channels 54.1 thru 54.11. I don’t receive EPG on all the channels from Gracenote. Only EPG data available for 54.1 thru 54.6.

Renamed the other db files and same result after tuner scan

Could it be a odd bug with the amount of substations on this channel? it has 14

I don’t think so. I have a station on the same RF channel as yours with 11 channels and it doesn’t have a problem. I don’t think that it matters how many.
Why don’t you try this: Uncheck all the 26.x channels in both tuners and see if the guide still shows channels 26.1 - 26.8, or note what changes you see in the guide line-up.

Son brought over his server running debian so it looks like the channels are in the tuner but not showing different server different hauppage quad card.

on his second tuner it doesn’t pull 13 and 14 and all of the other 26. channels are visible.
