Recording Pending Due to Hung HDHomeRun Connect

[PapaJay]

Hi

I just moved to NextPVR V5 over the Christmas break - I had been on V4. Everything has worked well, but I have run into one behaviour change between V4 and V5.

Background first:

• I have an HDHomeRun Connect with 2 tuners.  It is model HDHR4-2US(CA) if that makes a difference.
  
• It periodically hangs - this has been a problem for years and HDHomeRun support says it is the network in my house, which it is not, having replaced and rewired everything several times.  My son has the same set up but is running an older firmware level and his does not hang. (no more on this here unless it is needed to help with looking at the NextPVR behaviour change).
  

On V4 when the CTV National News recording failed because 'no data delivered' from the hung HomeRun, it would look for an alternate airing, in my case at 5:30 AM the next morning. Of course since the HDHomeRun was hung, this to would fail.

However, now that I am on V5 the recording at 5:30 AM is not failing, rather it is remaining in Pending state even though it is now 10:30 AM in the morning.  It is this pending state for the recording at the alternate time that is the behaviour change.

I attempted to clear the problem by doing the following:

1. Powered off the HDHomeRun and powered it back on.  Following this I was able to use NextPVR to watch live TV through the HDHomeRun.  However, the pending recording at 5:30 AM remained - it was not cleared or moved to failed state. 
   
2. I stopped and started the NextPVR service (using Windows services). This cleared the pending recording and placed the 5:30 AM recording in failed state with the message 'Recording service not running at recording time'. According to Windows services it was running - I am guessing it was just stuck. Restarting the service which effectively reloads and starts the program, cleared the problem as I expected it would.
   

As I said above this is a behaviour change between V4 and V5.  Could someone see if this is working as expected in V5.

Environment:

• Windows 10 PRO build 19041.685   On a home built PC.
  
• HDHomeRun Connect model HDHR4-2US(CA) firmware level 20200907
  
• NextPVR 5.1.0.201216
  
• There is single gigabit switch between the PC and the HDHomeRun
  

Logs collected after I cleared the problem are attached.

Thanks. PapaJay. Richmond Hill, Ontario, Canada

Definitely one for sub.

It looks like it's scheduling the recording, but not adding the power management request to make sure the machine is awake at that time, and your machine has gone to sleep in the meantime.

Yes, the machine is setup to sleep after 20 minutes of inactivity.  Normally the last recording, the local news, is done by 12:10 AM. However, I also run MCEBuddy to remove commercials and covert the over the air TS file to mp4 (to save space).  95% of the time MCEBuddy would be long done before 5:30 AM and the machine would be sleeping at 5:30 AM.

In this particular case looks like MCEBuddy finished around 2:40 AM, and the machine went to sleep around 03:02 AM.  The resume at 07:41 would have been us waking up the server (using Wake on Lan) to watch the recorded news from the last night.  That's when we discovered the failed recordings.

Further digging tells me that the HDHomeRun stopped sending data to NextPVR around 9:40 in the middle of a 1 hour recording - that recording is only 42 minutes long (2 minutes of pre-pad). So when NextPVR tried to record the National News at 11 PM and the Local News at 11:30 PM, it received no data.  The National News is rerun at 5:30 AM the next day, and NextPVR did a good job of trying to record it again, except that the server had gone to sleep, and there was no wake up scheduled.

I will be opening another problem ticket with SiliconDust about these hangs.  I have reported the problem twice before, and they have not been able to figure out what is going on, except to tell me that my network is broken or the network adapter in the HDHomeRun is faulty. As I said above I have rebuilt the network, and when failures continued I bought a second HDHomeRun. The second one fails the same way as the first.  I am certain it is a software problem - I just upgrade the HDHomeRun's firmware that was 2+ years old - failure times when from 2 to 3 weeks of running to 2 to 3 days of running with the new level.

Thanks for your support.  PapaJay

I've added the wake up request for the above scenario.
