Channels not detected in device scanning

Higgo · 2020-07-22, 11:43 PM

Hi NextPVR folk.
I have just moved to trying NextPVR after weeks of struggling with MediaPortal2 and then MP1. NextPVR was a pleasant surprise, however, there's been a major upset—scanning the four tuner device/s on a Hauppage receiver card hasn't detected any of my national (Australian) broadcaster's TV channels. The first scan yesterday retrieved 22 channels. Today when I retried, it retrieved 25, but still no ABC. The ABC constitutes the bulk of what we watch! Although MediaPortal gave me many headaches, both versions detected the ABC channels with ease. I've tried (perhaps inadequately) searching this forum and not found anything related.

I did find this page: http://www.nextpvr.com/nwiki/pmwiki.php?...WithOTAEPG that recommends ticking Scan Offsets as that's required by some devices in UK and Australia. However that appears to relate to an old version of NexPVR—I can't find that option in the current version.

Can anyone help me? I've attached the log file.

Are your scanning Australia - All Regions ?

You can try an increase in the time that NextPVR spends scanning for channels with an increase in the value of <scandroptime> in config.xml ... https://forums.nextpvr.com/showthread.ph...#pid542891

Thanks to both of you for your replies. I had tried scanning both nearest broadcast locations, but hadn't thought of scanning ALL Australian regions.
Thanks mvallevand, your suggestion worked! With that, NextPVR detected 56 channels including the ABC.

Hi all, sorry to drag up an old thread. I'm having issues with NextPVR finding the ABC channels in Sydney. TVheadend found them with no issues. I've tried setting <ScanDropTime> in config.xml to 10000 (default is 3000) but I don't think the app is actually using that setting as when I performed the scan, I see the line >>> Scanning 226500000 (the ABC frequency) changing in less than 10 seconds (around 3?)

Below is the console output when I run the scan manually. There appears to be a lock on the 226.5MHz but no stations found?

Yeah hijacking a thread is not recommended just to save creating a new one, the issue is probably not the same so many years later. In any case no logs no problems.
