Located in USA. Using USB tuner connected to Plex. Live TV & DVR features are working fine except that the programming guide for 1 channel does not reflect a recent change in local OTA programming.
Local OTA broadcaster changed one of their subchannels from DABL to DEFY earlier this week.
Plex guide and player still show the previous channel name (DABL), programming schedule, and episode descriptions. Iâve used both the Refresh Guide (many times) and Rescan to try to force it to reflect the change.
On a different device (TV w/ internal tuner) Channel ID and PSIP information is showing the new/current programming information (correct channel name [DEFY], program name, and program description).
The broadcaster is using TitanTV for PSIP/EPG data and TitanTVâs channel information is correct on both the TitanTV website and the broadcasterâs website.
Possible that Plex is pulling guide data from an out of date guide source? Where does Plex get guide data? Should I just wait and hope that the change shows up in other guide data providers? Or is there a way I can purge the guide data on my server and refresh with all new data?
Plex doesnât pull from Titan, unfortunately. Iâve had locals make changes like that and the Plex guide data has stayed âbrokenâ for more than 18 months in at least one situation. A couple of other times, I ended up finding a different 3rd party guide-using service (donât recall which one, unfortunately) that showed the same error (which confirmed they were on the same source) and reporting the error to them through their provided link. Within a couple days theyâd investigated and reported it to someone they had contact with and suddenly it was correct for both their service and in Plex. Trying to get guide updates passed through to the source level is difficult, and intentionally so, given how easy it could be for malicious actors to âpoison the wellâ for sport or profit or revenge or whatever else if it wasnât so difficult.
I wish there was an option to force Plex to prefer the over the air PSIP data as a primary for however many days a given station was serving in their transport stream, and then backfill with Plexâs data providerâs guide data to fill out the dates farther into the future. This would allow for better reactivity to last minute changes if stations were to update their guide on the fly, rather than waiting minutes or even hours for it to propagate out over the internet and then back to their multiplexing system. Only a pipe dream, unfortunately.
Thanks @NorCaDorka
I agree that having more options for guide data would be a huge improvement. Odd that we can customize the agents for all of our other libraries, but OTA is locked into a single system. Being able to switch to PSIP seems like a simple solution and would even be a great option of Plex installs that donât have WAN access.
Based on searching it appears Plex might be using Gracenote for EPG (found an old announcement about other countries moving to Gracenote, couldnât confirm for USA). There is a Gracenote customer support contact option to report issues, but itâs hard to saw whether this will make an impact.
The channel change has been recognized on other online sources. Rabbitears.info correctly identifies the new channel and I think their data is scraped from the FCC?
Guide updated to reflect the change today. Just took a long time (about a week) for the change to propagate throughout all the guide distributors I guess.
Iâve not seen where RabbitEars pays any attention to the subs, only the main channels themselves. If theyâre providing lookup for that data, theyâre getting it from one of the usual suspects, not the FCC. The FCC doesnât care or track whatâs being done with the subs as far as affiliations go, theyâre only licensing the RF channel slots that broadcasters modulate within.
