Issues watching one channel, new problem

[Ricknextpvr]

In the past few days, I have not been able to watch NBC Nightly News.  If I try to watch via the TV directly, live, it's fine.  With NextPVR, I normally start watching a few minutes in, and skip commercials.  Now, when I click on it, nothing happens,  If I try to watch live via NextPVR, nothing happens.  Watching CBS or ABC news, no issues.

My first guess was weak signal, but watching live via the TV directly says that's not it, coupled with watching the channel after the news ends works fine.  Now, with the little I understand about DRM, I'm wondering if they're encoding something that my old HD HomeRun boxes can't decode, but the TV can.  But why would they encode one program?  We watched a few nights ago without issue, as well as a program recorded on the same channel, Transplant, without issue.  So it seems to just be the Nightly News.  

I've attached the logs to see if they show anything (news is 6:30PM tonight), but if there's anything I should look at during the broadcast please advise.

I had looked into updating to the newest HD HomeRun boxes to take advantage of my 4K TV, but it appeared to me that they're having DRM issues also, and it would simply be wasted money.  It's also unclear to me how many shows are broadcast by the major networks in the top resolution.

I've been exploring things in planning for the demise of Windows 10, trying to figure out the best long term solution that doesn't break the bank.  I was thinking switching to Linux Mint on the same PC I'm using now (assuming I can figure that out).

Any insight into my current problem is appreciated.

You NBC issue is signal related, you might need a rescan or some antenna changes

2025-06-29 18:27:08.686 [DEBUG][4] locked=0, present=0, strength=0, quality=0 (took 0ms to check)

The only DRM is on ATSC 3 channels which won't impact ATSC, except sometimes ATSC1 is on weaker towers.

I would suggest using the Silicondust HDHR utility "C:\Program Files\Silicondust\HDHomeRun\hdhomerun_config_gui.exe" and seeing if you can tun NBC on physical channels 32 or on another frequency. If it finds it you need to rescan in NextPVR

Thanks Martin, that is exactly the logic I was following, until I realized that the same channel records fine for the show midweek, and right after the news. How can there be no signal at 6:27 yet a signal exists at 7:15?

Update:

I have 2 HD HomeRuns. Each with 2 tuners. On 3 of the tuners, I can tune to 32. On the 4th tuner, it won't do anything but 20...

I wanted you to check the app to see if it was consistent and good quality. The successful views took a few seconds to lock which is a lot for ATSC

The one tuner issue seems to have resolved itself. I have rescanned both in NextPVR, then deleted and refreshed the channel guide.

As an experiment, I have set recording tonight for the 6PM local news, then the 6:30 National News, then the 7PM game show. It will be interesting to see what, if anything, has issues.

Signal strength isn't the problem, NBC is 66%, as is ABC which works fine.
