So, since nobody came to help, I eventually found a way to fix this in this thread.
I had tried reconnecting & then removing the tuner, that seemed to work, but then after a day the error came up again, I repeated the process, adding the tuner, then adding 2 of my other tuners, then deleting the old one, then restarting, then deleting one of the others, then restarting, then deleting the whole DVR again, & that seems to have done the trick. Then I discovered that the one with the Non-MAC letters was a virtual HDHomerun I used for like 2 weeks either at the beginning of COVID or possibly before, I’m not sure, but there wasn’t really a way to re-add & remove it like I had the other.
I then started looking for a way to completely remove my TV Tuner & DVR Data completely, even though I had essentially done that through Plex, it seemed that Plex still stored it somewhere that came back to cause trouble years later & I didn’t see a way to do this for the other problem.
Then I found a thread about Deleting All Tuner Data
Delete All Tuner Data - #7 by Brandon0413 . So I went about getting the non-install version of SQLiteBrowser (32bit), made a backup of the com.plexapp.plugins.library.db database, & found the media_provider_resources table & just deleted all the rows of the table by finding the table in the Browse Data tab, right clicking on the number of each row on the far left, & selecting Delete Record (I’m pretty sure I could have done multiple, but there was only 10 so I figured better safe than sorry since I didn’t know if Ctrl-A. selected anything outside of that table or the table itself or just the data in that table.
I discovered that Plex keeps the data from every tuner you have ever used with no easy way to delete those, & it seemed to have the same tuner twice for a few of them, & there were a couple PCIe & USB tuners I tested to be sure they worked fine before using them in a system I built for my dad. So if the same thing happened later with those…
Now I just wish there was a way to search the SQL Browser to see what the other errors are being caused by.
IncludeExternalMedia & libraryHubsOnly & contentDirectoryID & pinnedContentDirectoryID that QueryParser keeps having a fit about,
ID 80746 that perhaps was merged with another item,
whatever is Missing X-Plex-Container-Size header,
& especially Subscription: Error refreshing sub: Could not find providers for subscription because that is what I see more than anything.
I had old plugins that I tried removing, thinking maybe those were the problem, replaced all the credentials for SubZero Sub agent because it seems to be about subtitles that possibly, but none of that solved that one.
But the HDHomeRun issue is at least solved
Edit: This is marked as the solution because it gives a solution, though not a great one, for the [Bug] this thread is about. If a better solution exists I’d still appreciate hearing it & I’ll switch the solution marker unless I cannot for some reason after a set amount of time or something.
Also not that Comment 3 Is also a solution, & a very helpful one, but to other issues present in the log, not the DVR one.
