Recording started 15mins after scheduled (5 mins after show started airing)

Yes, I do, because I don’t want it to cut off any of the next show. Based on issues that others are having, I could lose 15 minutes of the show if I check that box.

@sa2000 OK, here’s another one - this time a 20min delayed start to Hawaii Five-0 (relative to the pre-buffer point).

Note: in the shot below, you can see I have already deleted Hawaii Five-o as the episode did not full record due to the late start. Superstore recorded fine but I have moved it.

I had the usual 10 min before/after buffer so recording should have started at 19:50:

HDHomerun logs show that Tuner 0 was initiated at 20:10 (20 mins late to the pre-buffer) and 10 mins after the program had actually started. The tuner closed correctly at 22:10ish after S.W.A.T had finished. It’s also worth noting that all 4 tuners were in play at 19:50.

I’m somewhat confused as it shows tuner 0 (the one that should have been recording Hawaii Five-0) as being in use until 18:10, the point at which it did start recording Hawaii Five-0).

Tuner	17:55	19:20	19:50	20:10	21:10	22:10	22:15		
	0	-		ITV2---------->	Pick----------->	
	1	5USA--------------------------->
	2	-		-		Horror--------->
	3	-		-		ITV3--------------------------->

So maybe there was a conflict on tuner 0 that Plex failed to recognise?

Plex logs show that Plex recognised the start time of 19:50. I have attached 4 logs as that’s how many covered the 2 hours 20mins in question. This is the start point (from log 4):

Forgot to add that Plex thinks it recorded Hawaii Five-0 successfully (despite starting 20 mins late etc etc):

I have looked at your logs and I can see the transcoder job exiting after it failed to get the data for the offset it wanted from the earlier channel recording job - I have referred this to the development team. Could be some timing issue

@JCHH sorry i have not had time to look at your logs - but have referenced them from the issue I opened up for @mbarylski

Awesome, thanks!

Cheers.

Any update to this?

In a possibly unrelated issue, I have noticed a few other things:

  • Plex no longer always records at the first opportunity (despite no scheduling conflicts); it sometimes records the “+1” or second airing instead - no clue why
  • Plex sometimes records an episode or - in my case - complete series that I have already downloaded. My specific case: I have every episode of “Stargate Atlantis” except the last one so I set Plex to record. However it is re-recording every single episode. It is not doing this with other series in similar situations. The only thing I can think of is that I am now on the new Plex TV scanner, but when I search for Stargate Atlantis both the existing series and the DVR series show up.

Is it worth starting new threads for these issues?

[edited for typos]

Yes - I would suggest that.

For this PMS either fails to match the episode in the existing recording library or using option to find better resolution - anyway logs would be needed and may also need metadata xml for the existing episodes that get recorded

It’s defo not this (I checked) but understand re logs.

@sa2000 I think we may be able to crack this now. I believe there is a logic problem with Plex’s tuner…

Yesterday, Plex failed to record the 1st 10 mins of Doc Martin s06e03. The schedule was as follows:

			20:00	21:00	22:00	23:00
010 ITV3	e03 -->	e04 -->
058 ITV3+1			e03 -->	e04 -->

e03 missed the 1st 10 mins
e04 was fine.

The HDHomerun logs are as follows (remember times are GMT) :

…The HDHomerun logs look like this when charted:

BST		19:50	20:10	20:50	21:10	21:50	22:10	22:15	23:10	
GMT		18:50	19:10	19:50	20:10	20:50	21:10	21:15	22:10
0	 	------>	<free>	ITV3 ------------------------->	<free>
1		5 USA ----------------> ITV3+1 ------->	<free>
2		Horror --------------->	<free>	CBS J ---------------->	<free>
3   	Pick -----------------> <free>

As you can see, had Plex tunes tuner0 to ITV+1 at 20:50 (19:50 GMT), it would have caught both episodes.

But wait, it did:

20210528-19:50:02 Tuner: tuner0 tuning 58 ITV3+1 (t8dvbt:538MHz-16016)`

But it then immediately retuned to ITV3 thereby missing the 1st 10 mins…

20210528-19:50:26 Tuner: tuner0 http stream ended (remote closed)
20210528-19:50:26 Tuner: tuner0 tuning 10 ITV3 (t8dvbt:658MHz-8294)

So it made the right decision, immediately followed by a flawed decision.

The question, therefore, is why did Plex do this?

20210528-19:50:02 Tuner: tuner0 tuning 58 ITV3+1 (t8dvbt:538MHz-16016)
20210528-19:50:26 Tuner: tuner0 http stream ended (remote closed)
20210528-19:50:26 Tuner: tuner0 tuning 10 ITV3 (t8dvbt:658MHz-8294)

Logs attached (7 logs cover this time period). I have a local copy of all the logs if anything else is required.

Thanks for the detailed investigation. I have added all the above to the open issue I have with the server team

Thank You
