yes, that original file look odd - thanks for checking this.
Hi @sa2000
Here’s another similar one. This time my logs caught it - 20 logs go back 48 hours (which indicates I am still logging too much).
Regardless, here are the details:
I was recording 2 episodes of MacGyver on Pick yesterday - both with 10 minute pre/post buffers.
The 9pm aired fine, the 10pm did not.
Plex thinks it recorded though:
10pm file has (0 bytes)
My HDHomerun logs show nothing happened for the 10pm recording:

…nothing for 10pm MacGyver
I have attached all the logs, but it kicks off in #7 - there are over 1000 entries for 20:50 alone.
Appreciate your help on this.

Here’s a 2nd one - hopefully you’ll be able to look at both and figure out why I need 10 logs/day next week 
Plex says “All Creatures Get and Small” s04e04 was not recorded this morning on Drama +1 this morning. Interestingly, there should have been. no reason why it did not record an hour earlier on Drama (as there were no conflicts).
Detail screen said: “airing as already in progress”:
Below Arte all the HDHomerun logs from this morning. As you can see, no tuner was used (again):

My 20 logs still only go back 2 days, but that was enough - Log 1 has the correct timeframe, but have attached all anyway (because 48 hours is still a problem).

Thanks!
I started looking at this.
Looking into “All Creatures Great and Small”
So the airing for Season 4 Episode 4 The Pig Man Cometh was starting at 02:50 am 1st May on 020 Drama and at 03:50 am on 073 Drama + 1
Throughout the time up these start times, the episode appears to have existed in the library - the first time when it was no longer in the library was at 04:04 am - The recording got started and aborted as the program had already started.

I am not sure why the current logic resulted in an attempt to start the recording then - only to realize that would be a partial recording and then aborted
So for this example - it did not get recorded at the right time because Plex Media Server believed it was already in the library
I will look at the other example MacGyver and also see why logs filling faster than before.
Cheers. Is this something the devs need to look at?
There was a transcoder failure for the 2nd recording which got appended to the first transcoder job that was capturing the channel stream
Apr 24, 2021 21:50:15.686 [0x7f964ba23700] ERROR - [Transcoder] [mpegts @ 0x132e4c0] sample rate not set

I do not know why the transcoder failed in this way. Is back-to-back recording for same channel with 10 minute pre/post buffers working at other times ?
I need to establish if this is reproducible or some timing issue
I do back-back all the time - but need to confirm it is the same channel - not sure how to do that easily though.
…but Plex should know whether it is possible or not and have given me the warning triangle if not. possible,
It should be possible - don;t know at this stage if this is a one-off or a regression
Another thought; I have a 4 tuner HDHomerun and they were not all in use. If Plex can’t handle back-to-back on the same tuner, why didn’t it use the spare one?
I’ll try to look at my HDHomerun logs today and see if it has been doing back to back before (or is there a dev you know who can answer this)?
I have just tested back-to-back with a 2-tuner HD Homerun and i had 3 recordings of 15 minute episodes on one of the children channels with 10 minute for pre and post amble for each - and all 3 recorded ok,
Will need to see how your issue can be reproduced
Any more examples of these recording failures?
Actually, I have had a few but wasn’t sure if other examples would help
I’ll try something similar and let you know.
OK, in summary, it worked - but have kept logs which I can upload if you want…
I scheduled 3x 1hr shows and 2x 30 minute (back to back) shows:
Everything recorded OK. Here is a screenshot of the overlap with all 5 shows recording (on 4 tuners):
Ignore American Pickers and Emmerdale - that was just me trying to find the right shows to record.
Here is the “after” DVR Schedule status:

Is anyone seeing this error when the show fails to record? This seems to happen when 2 shows are on the same channel back to back. I had the same thing happen with The Flash and Supergirl on CW. I have 6 tuners, and with the recording tonight, only 2 were needed, but it still failed to record. @sa2000 I have logs if you have a chance to take a look at them.
yes, that’s exactly what I posted further up the thread here.
Can you post the logs?

Thanks. I’ll send the logs over to sa2000. This is happening to me all the time now. It just started about 2 weeks ago from what I noticed. It might have started sooner though and I just haven’t noticed the other missed recordings yet.
@sa2000 I sent the logs in a DM. Let us know if you find anything that might help point to a solution or if you need any more logs.
cool.
BTW, I don’t think there are any privacy issues posting the logs here - the advantage being that other people “who know” can also advise when @sa2000 isn’t around.
Do you have “Allow partial airings” enabled in the advanced settings for the items experiencing this problem?
If disabled, and the recording cannot start immediately for some reason, it could cause the recording to fail in this manner.
