Plex DVR, Trying to watch Live TV but get error "Unable to tune channel (no parts)"

So I scheduled 8 recordings to start at 11 am with 6 of them being 30 mins long and 2 hour long.

All 8 recorded it appears with no issue. Of the six 30 minute ones only 4 of them were sent to post processing and the other 2 were added directly to the library. Once the 2 hour long ones finished they were added to the post processing queue…

I’ll keep monitoring . . . I have 9 shows at various times tonight . . . so I’ll be watching and monitoring them.

I need to start manually updating PMS so I have previous versions saved in circumstances like this.

I’ve been dead in the water for over a week now and it forced me to try Channels DVR. So far I haven’t found a reason to stop using Channels DVR…

But I would still like to see Plex DVR work.

@sa2000 are you still looking for logs when this occurs, or are you able to reproduce? It definitely happens frequently if I use Live TV as I mentioned above. If I don’t use Live TV or restart PMS after using Live TV, my recordings are pretty solid… Just my 2 cents.

I am not looking for any new logs for the following issues

  • Tuning errors when attempting to start a scheduled recording that follows an earlier Live TV use of channel.
  • Failure to tune due to timeout - seen mostly on PCIe and USB tuners but also seen on networked tuners

12 days short of 1 year since the problem was initially posted and this is still an issue!?!? I’m seeing staff members asking paying customers to run WireShark!?!? At what point does Plex refund the money for a product that simply continues to not work as advertised? I’m seriously considering issuing a charge back for this service as it does not operate as advertised.

I mentioned this on support for billing and was just referred to the forum for technical issues…

I’m in the UK and getting this issue from time to time running 3 WinTV DuoHD tuners on Plex Version 1.13.9.5439 on Ubuntu 18.04LTS… I’m really surprised this issue hasn’t been resolved at all!!
They really do need to sort their act out and forget adding new stuff to Plex and concentrate on fixing bugs like this, else they risk becoming like Microsoft have with Windows 10 bugs… lack of testers???

With the Windows 10 bugs, there were identified by the testers, but MS didn’t listen to the testers. They’ve since revamped their bug reporting process and allow users to flag critical bugs like the data loss issue to the devs attention. The thing with Windows 10 is that, for the most part, it was free for users. MS has offered free upgrades since Windows 8.
Now with Plex, if the DVR functionality was free I wouldn’t be so upset about all the issues with the product. I would take my time/effort to help with submitting logs to the devs in hopes to make the product better. All I want to do at this point is to get my money back and move on to a working product.

The actual issue I’m having affects 3 channels, especially when we’re watching one while recording the other, it’s when the recording finishes it trips the Transcoder or when we’re watching one of the other channels and my 3 year old son is watching the cartoon channel and we change from that to say an HD channel or vice versa, the transcoder goes into a wobble then shows up the message “Playback Error”
This along with Photo uploading from our phones was one of the reasons we became Plex Pass users, but since it seems the Dev’s are more interested in adding Web Shows, which sorry to say are not that good, they seem to have let the other sections go! This needs to be fixed and soon, as I’m beginning to feel I’ve wasted over £100 on 3 WinTV DuoHD receivers to cut the cord totally and save our family money on subscription TV. The issue doesn’t happen on Movies or TV shows I have on the other hard drives, just the Live TV…

So if any Plex Dev is reading this, please fix it soon as it’ll make a certain 3 year old happy and my pregnant girlfriend to… Oh plus my Ex-Wife who thought it was me messing with the server!!

How does one get rid of dead DVRs in the Plex database? Plex is trying to contact them repeatedly and marking them as dead repeatedly.

Perhaps these ghost DVRs are causing issues with tuning.

Go to settings / server / manage
Live TV & DVR
and Delete the unwanted DVR’s

Well that’s just it. They aren’t displayed in the Plex interface, so one can’t delete them from there.

They are in the database and Plex tries to contact them.

I’d say there’s a cleanup bug in there somewhere.

I think I have that same issue. I deleted the HDHomeRun device from Plex but keep getting this in the logs:
Plex Media Server.5.log:Oct 22, 2018 13:46:44.063 [0x7fe1febff700] ERROR - DVR:Device: Error refreshing existing device device://tv.plex.grabbers.hdhomerun/1325DF61, marking as dead.

Need to look at the database

Could I have screenshot of the DVR setup screen and the logs and the database zip sent to me by private message

Please make sure debug logging is enabled beforehand

I used an SQL database tool to manually delete all the DVR entries from the database, and then re-added the DVR. There were six or seven rows with DVR entries in them.

Tuning works much, much better now, based on a brief test.

Sorry I can’t help with the database info.

Tried to send a PM, I think it ended up as a thread of some sort.

Got the export. of the table
Is this happening on both of your servers
Which version / build when DVRs were deleted

Only using DVR on one server, Windows 10, currently on Version 1.13.9.5439. It is happening with this server.

When telly was removed, I was on whatever the previous plex pass preview version was. Sorry I can’t be specific.

However, failed cleanup of deleted DVRs seems to happen with both and should be easy to replicate.

What table contains these dvr references - I copied the db over to another system to see if I had that problem as I have deleted and added tuners many times over the course of the last few months - but I could not find the table that contains the tuners…
