This is strange. I’ve got 3 tuners, but this morning I noticed 1 of my recordings failed with the message, “The recording was not started because airing was in progress.” Only 1 tuner is in use at the time of the error. Why would it think that the airing was in progress? They are 2 separate “airings”.
Maybe because you don’t have “allow partial recording” in the programme?
That happens if you tell Plex to only record “complete” airings.
If you created the recording job while the airing was already in progress (or you started Plex server while the airing was already in progress), then Plex won’t start the recording and wait until (and if) it is re-aired.
But I didn’t create the recording job while the airing was already in progress or start the Plex server while the airing was in progress. The recording was set up the day before. I wasn’t on the server at 5:30 AM. The recording was scheduled the day before. I shouldn’t have to Allow partial airings for it to record 2 shows at the same time when I have 3 tuners right?
In theory not. Were the two recordings tuned to two different channels? (i.e. one requires HD, while the other does not)
Or maybe was the tuner device in use at the time, by something other than this particular Plex server?
The tuner device was only in use by Plex, but the two recordings were probably on the same channel. Regardless of channel though, it should find an open tuner if 1 is already in use.
Details why this didn’t work can only be found in the Plex Media Server.log from around when the recording was scheduled to be started.
And only if the server logging was set to “debug”.
Don’t forget about the ‘Padding’.
I can’t recall if padding is shown in the image you posted, but if episode 1 is padding the end when episode 2 is supposed to start and tuners 2 and 3 are doing something else (like Padding) - there won’t be a tuner available.
As eluded to - the logs will tell the tale.
Ok, I’ll enable debug and send logs if it happens again. Maybe it occurred because it got confused by the 2 HDHomeRun Primes that I have. 1 with a CC and the other without. I moved another CC to the 2nd HDHomerun Prime, so we’ll see if it happens again.
@JuiceWSA Overlap doesn’t explain it at all since there was only 1 tuner in use at the time. The DVR should be recording the next show on an available tuner, not trying to take a tuner that’s in use.
This happens when you have back to back programs recording on the same channel and allow partial airings is NOT selected. Allowing partial airings will fix this. PMS will not tune two tuners to the same channel.
Yes, it will do that on some newer models. It certainly does on my HDHR5-4DT.
I can use whatever padding I like. It always uses only one tuner for back to back recordings.
In your case, with the newer HDHR it preserves an overlap and somehow records the last minute of the 1st show and the 1st minute if the 2nd show on the same tuner? At least that’s how I understand it from another thread where this was discussed. I believe 2 tuner devices might be an issue though. Weird thing is, I’ve been recording back to back shows on the same channel for several weeks. I’ve turned on debug now though so if it happens again hopefully it’ll be easy to pin down why.
When I looked at the logs when this happened to me, PMS for some reason attempted to start the recording a few seconds late, and aborted because allow partial recordings was not enabled. It only happened when back to back recordings from the same channel were happening. I’m using a HDHomeRun Extend (HDTC-2US, 2 tuners).
This also happened to me in the small hours of this morning trying to record the two episodes of Battlestar Galactica that are shown weekly (back to back) on BBC2 HD:
The first episode recorded okay but the second did not 
Like others I do have Allow partial airings disabled.
I’m using a HDHomeRun Connect Quatro (HDHR5-4DT) and no other tuners should have been in use at the time.
I will try and take a look at my Plex and HDHomeRun logs.
Inspect the details of the two airings in the EPG.
If there are no further details in there which allow Plex to differentiate the two, it will assume that the second is a re-run of the first and thus won’t record the second.
Cheers… I believe Plex thought the two episodes were:
I have found that if there is an issue on the server that causes the recording to try to start a few seconds late, it will not be started because it was already in progress.
For example, the server was stunned due to a snapshot being taken.
I always allow partial airings because of this.
Ah - I’ve started to go through the logs, but there is a lot of information in there when debug is enabled, however I thought bug fix #11916 was supposed to fix recording starting a little late?
Yes, you would think that would help. Can you see from the logs if the attempt to start the recording was more than 30 seconds late?
