NextPVR - Failing with HDHomeRun Quatro

[guyinco6nito]

Hello,

I've built a new recording station using Windows 10 LTSB 2016 (like my old recording station that worked just fine) but I'm having a heck of a time getting NextPVR to work with my new HDHomeRun Quatro.

NextPVR can find the devices, it can scan the channels, it can download the guide from SchedulesDirect, but when I try to watch Live TV or schedule a recording nothing happens. The Log says:
 "non-existant capture source: 20"

I first encountered this with the latest NextPVR 4.2.5 with my old first-gen HDHomeRun device (which worked just fine on my old recording station).  I then hooked up a HDHomeRun Quatro hoping that the newer device supporting DNLA might work, but I had the same problem.  Then I downgraded to NextPVR 4.2.2 (which I was using on my old recording station) and encountered the same problem!


I've tried the advice here: https://forums.nextpvr.com/showthread.php?tid=54068 and changed the BDA Compatiblity mode in HDHomeRUn setup to be Default and MediaPortal but there was no change.  I tried disabling the Windows Firewall and there was no change.  I know the device works because I can view the changes from the HDHomeRun Setup tool, and because NextPVR is able to scan for my channels just fine, however I cannot tune or record them.  I've attached my logs, is there any chance they indicate some problem I missed?

Thanks much for any advice you can provide!

Have you tried rebooting since setting up?

Disclaimer: It's been a while since I've working with v4 now, so I may be recalling things a bit off...

Which device type are using the HDHR one or the ATSC (or QAM) one? You mention the BDA Compatiility mode setting which only affects the ATSC/QAM device types. But you also mention changing to the newer device type which implies using the HDHR device type (which streams from the device using a different method).

If both systems are configured exactly the same way, it shouldn't matter which device type, but (at least for testing), it's probably worth trying the other device type.

At this point, I'd also suggest using v5. Technically right now it is still labeled "beta", but sub is planning to remove that label very soon. And several of us have been using v5 "in production" for a while now just fine. Also, if there is any sort of bug in NPVR, any fixes are likely only going to be for v5 now.

Hi All,

A reboot didn't change anything, but I upgraded to v5 and it works like a charm!
This interface is amazing and it was able to import my scheduled recordings from the old version.

Thanks much for all of your work on this!
