    Unable to scan channels with HDHR3-DT

    I'm having trouble getting the my HDHR to scan channels. The tuners are detected, but no channels appear when I click the "Scan Channels" button.

    I noticed this error in red when scrolling back through the Terminal window:

    [25] Unexpected error in legacy scan: Newtonsoft.Json.JsonReaderException: Error reading JArray from JsonReader. Current JsonReader item is not an array: Null. Path '', line 1, position 4.
    at Newtonsoft.Json.Linq.JArray.Load(JsonReader reader, JsonLoadSettings settings)
    at Newtonsoft.Json.Linq.JArray.Parse(String json, JsonLoadSettings settings)
    at NShared.Recorders.HDHomeRunScanner.LegacyScan(HDHo meRun device, Dictionary`2 parameters, String& reason)

    Is anyone else having this issue? Have I missed a step?

    I've attached my logs, too.

    If you open http://10.0.0.43 in your browser, are you able to find your channel lineup? I think it might be in http://10.0.0.43/lineup.html, but I'm not 100% sure. If not, are you able to scan in the web app and find your channels? (then restart NextPVR and try again)

    The HDHR page only has options to download instructions or firmware. I am on the latest. Is this tuner supported? I used it with v4 on Windows, but I use Mac more often so I'd like to use that if I can

    Is this tuner supported
    I'm not 100% sure with these older legacy HDHR devices on the mac. Hopefully it'll work though.

    This first thing it seems to be failing on doesn't seem to be mac specific though - it doesn't appear to have a channel lineup on the SiliconDust server. Usually these devices do, which is what made me think you need to do a scan (and then it'll upload the results to the SiliconDust server). If you do a channel scan in the HDHomeRun Setup utility on your Windows machine, then restart NextPVR on your mac, does it make any difference?

    You were absolutely right. I ran the scan using the Windows HDHR utility and it configured my channels. I now have them mapped and the EPG is set up, but they don't play.

    I'm wondering if it might be the tuner support after all? Would you mind having a look at the logs?

    It looks like it's most of the way there now.

    These old legacy HDHR devices it needs a utility called hdhomerun_config. That is available on Windows and Linux. I'm not 100% sure it's available on mac. I'm guessing it is available, and I think it'll be installed with this:
