Does that stream play in VLC?

I'm pretty sure that 'Connection refused' text is not generated by NextPVR itself, but comes from the HDHomeRun response.

Could you maybe have had something else using that specific tuner? It's worth noting, NextPVR does ask for a specific tuner, not just an available one.

Either way, it shouldn't have that NullReferenceException anyway, so I'll check out possible causes.

[rkulagow]

Weird. No, it doesn't work in VLC either.

However, it does work when I use the HDHomerun application on my Windows 10 machine. (I'm tuning to channel 2.3, so it's not using my HDHomerun Prime; it should be the HDHomerun OTA classic.

[mvallevand]

Does the HDHR web page log give a better idea of why there is an error or if the tuner is in use?

This is probably a silly question, but are you sure that the HDHR is currently at the IP address 192.168.10.168?

[mvallevand]

This is not a silly question but I am tending more to that being a legacy device based on the initial thread https://forums.nextpvr.com/showthread.php?tid=60955 using the http protocol.

This is why logs not snippets are good.

[rkulagow]

It is a legacy device, but I've confirmed the IP address is 192.168.10.168; I'm able to access the web page:


HDHomeRun DUAL
Model: HDHR-US
Device ID: 10160B31
Firmware: 20200225
Download drivers
Installation instructions

I'm taking another look ta this legacy HDHR tuning.

I think the change I made in the last release must have fixed your scanning, but didn't quite get it entirely right, so it's trying to do a modern HDHR style tuning over http, instead of the legacy tuning with rtp.

[rkulagow]

I'll be happy to test the next version of code; looking to migrate from my existing PVR to something different.
