DVR randomly stops recording - unknown error

I’m running Windows 10, using the DVR feature with a HDHomerun Prime box. It records properly most of the time. Recently I’ve been randomly having it stop recording shows with an exclamation mark and it says “unknown error”. All the future scheduled recordings will ail until I exit and reopen Plex server.

Is anyone else having this issue? Any idea where to look for a solution?

I’ve been having something similar on Plex Media Server for Ubuntu 64bit. Every few days it will fail a recording and then fail all subsequent recordings for all shows until restarting plex. Very irritating, I just updated to 1.7.3 from 1.7.2 in the hopes that it will fix the issue. We’ll see how it goes. I don’t have much hope as the issue has been with me for a few versions now and isn’t mentioned in the changelog as being addressed. Must only be affecting very few people as searching the forums hasn’t turned up much.

Try updating the firmware on the hdhr, they just released a new one a few days ago…

Also, does it actually start and then stop recording? Or, is nothing recorded for that one.

The reason I ask is that what I am seeing is Plex doesn’t seem query the tuners to see if they are available and just tries to use it. In that case, nothing is recorded for that recording.

@JeffCrum You are correct Plex doesn’t check the tuner. It assumes if you configured the device/tuner in Plex DVR then you obviously intended for it has exclusive access to the tuners. Since it assumes it has exclusive access it checks to see what tuners configured are available and uses one that is free in the Plex pool of tuners. If you are using that particular tuner in some other application outside of Plex the tuner will not respond to the request from Plex and your recording will fail.

Hopefully in the future they will add logic to query tuners perhaps 30 seconds before the show start time, including any before minutes we establish for the recording, to determine if it is available. If it is then it will start the recording using that tuner at the appropriate start time, if not it could then check for the next tuner until an available tuner is found or all tuners have been checked.

@johnm_ColaSC I wish that were the complete truth. But, I ONLY have my tuners defined to Plex. Except for testing setup and stuff, I don’t use my tuners for anything. They have not been touched by anything in three days. I’ll test three recordings.

Actually, I’ll reboot everything and test three recordings.

Same here. Tuner is only used with PLEX, and was working fine for the first few versions of the DVR beta. It does record and properly save content until…whatever error happens happens. At which point all future recordings fail as (as well as the current recordings) and PLEX media server itself eventually becomes increasing unstable until remote playback is unusable, and local playback has to have the quality severely reduced for smoothness. I updated PLEX to 1.7.3 today and have yet to experience reoccurrence, but it usually takes a few days to start failing.

I have not attempted the firmware update suggested by ssuess, I may have to. I do have some reluctance as the DVR was functioning fine until recent versions of PLEX media server. This makes me think that it is probably PLEX that is the issue. I’ll try to save my logs next time as well as a few crazy screen shots of the DVR page.

Already freaked out again… only with 1.7.3 this time. I may roll back a few versions and see if that helps. I can’t remember what the last working version was though…

The screenshot is what it looks like from the PLEX web access when the DVR goes haywire. I took it of todays agenda view around 4:40PM local time. The last show actually added to my library was a kids show recorded yesterday at 5pm. All the content in the screenshot with the full recording circle was not added to the library. See also that the DVR setting screen says that it is currently recording 19 to a two tuner homerun connect. Logging into the actual tuner shows no recordings at all. I have logs as well but don’t know which or where to share. Sorry, I’m not too pro at this.

For now i’m going to try rolling back to 1.5.6. I think that was before we had issues. If I have issues still then I’ll blame the tuner and try a FW update there.



My experience is that if there’s no data for Plex to record, instead of waiting a bit longer, Plex will completed the recording even though there’ll be signal coming in another 20 seconds or something. Sometimes my OTA does not have very stable signal, Plex will cut recording short. And this should be fix, as long as the schedule permit, Plex should wait for stream even though signal is not available for sometime. If not, at least, plex can tell the user, some error happened to the recording instead of finishing it like nothing happened.

added my issue to this bug report.

Looks like there are improvements coming for the transcoder that may help weak signals that are causing problems.

Thanks, that may help the OP, but signal is not my issue. It worked fine until recent updates, and now works fine again since I’ve rolled back to 1.5.6. Clearly a PMS bug for me, not a signal issue.

I too am having these issues… I wonder if it’s due to a poor signal or something to do with comskip. Will try turning that off temporarily to see what it does (if anything).
