Any idea if this is important?  I had a few recordings fail and saw this dump file by chance.  I am guessing it is an error with the tv tuner not locking signal causing some other issues possibly triggering the dump file.  The recordings in question are all on the same frequency so it most likely was just a tuning problem.  I am able to lock signal on that frequency now.

It look more like a problem releasing the tuner after recording.

2022-12-24 12:00:08.161 [DEBUG][4] Async stop taking way too long

Does N:\npvr recordings\DROP FOLDER\Bob Vilas Home Again\Season 16\Bob.Vilas.Home.Again.S16E15.Preview.of.Victorian.Kitchen.Remodel.ts exist on disk and does it show up in NextPVR web.

Note that SPMC and Kodi 17 are no longer supported.

----------No, the show does not exist on the disk or nextpvr web.

Ok thanks not sure if that will help sub or not but it might.

Is it a specific channel you have this problem on? (it likely is, and we'd need to identify which channel, and capture a sample stream from it)

I am getting zero byte files so something is conflicted.  The channel is 55 and frequency is 17.  I attached the sample recordings of zero bytes and log file.

You'd need to use the evaluation version of TSCapture (from https://tscapture.com) to capture a 1 minute 'full transport stream' of the channel, then put the file somewhere like onedrive or dropbox and let me know the download location.

I literally cannot tune to channel 55 with hauppage device using tscapture.  It's like the hardware is actively denying that channel.  I can tune to it in nextpvr but it is probably using my silicondust hdhomerun.  So, I am for the time being going to delete channel 55 from hauppage devices and force nextpvr to use hdhomerun to tune that channel.  The signal quality is 50% in hdhomerun config so I may need to play around with antenna. I have several months of recording at this antenna position, so this is weird that signal quality has dropped 20% overnight.

You probably need to tune using the physical channel 17.

I meant to say physical channel 17 but local channel 55.  I think it is just not getting good signal, but you would think ts-capture would have a lower bar for signal quality and include anything on the margins of watchable.  Even my hdhomerun config tech signal viewer is +/-10% (57-67) when tuned to 17-3 (55.1) on my 2 virtually identical hdhomerun devices off of same coax splitter (-3.5db each).  Here is the link to the ts files captured from hdhomerun using ts-capture.  I did three separate recordings.  With my hdhomerun only tuning of 17 (55), the recordings are working without issue.  I picked the best hdhomerun device for tuning 17 (55) and deleted the channel from all the other tuners.
