Windows 2012 - NextPVR - HDHomeRun Dual - Won't Scan

[dth4310]

I've got a Win 2012 VM (on a quad cpu with lots of RAM using lots of raw disk maps) and an HD HomeRun Dual I would like to put together to create a sweet PVR backend solution for XBMC. I don't have cable, so going with just OTA ATSC signals - about 30 channels. I've gotten the HDHomeRun connected, and can successfully view channels via quickTV and even from XBMC with the .strm files.


Unfortunately, I'm having a heck of a time getting NextPVR to properly pick up on ANY channels. I've checked firewall rules for all executables, and even disabled the firewall so i'm "pretty" sure that's not the problem.

I duplicated the state of affairs by trying to get nextpvr working on a physical win8 machine; appears to have same issue.

Running HDHomeRun software of 20130328 - NextPVR 2.6.2.

When the HDHomeRun primary device is set to either NextPVR - Other: ATSC/QAM - I get the following error when trying to scan on the HDHR device:

Code:

When I try to scan via the ATSC device - I get the following:

At this point, not sure what to try next. Any advice appreciated.

Try using your web browser to go to http://192.168.1.135. I'm pretty sure there is a scan button somewhere in the web site - click it, then see if it helps in NextPVR.

[dth4310]

The only links that I can see when i point a browser to the HDHomerun unit itself are links to the Silicondust pages for driver downloads / instructions...no actual "usable" buttons. If i head to http://192.168.1.135/lineup.xml - it's an empty xml file. I can scan successfully through the hdhomerun setup util.

On the Settings->Devices tab you should be using the 'ATSC' device option. Don't use the 'HDHR' or 'QAM' options. They're both for digital cable.

Can you see if running the app with 'Run As Administrator' helps get you past this?

[dth4310]

I launched NextPVR as administrator - see the same message in logging.

I added a response earlier but I deleted it based on sub's reply. Is it possible that the digital tuning interface IATSCLocator requires BDA drivers which aren't available in 2012 server?

Yeah, could be something like that.

I'll give a shot on a win 8 MC VM to try for a different result. I attempted very briefly to setup on a physical win 8 laptop with similar issues...but didn't spend much time troubleshooting. Thx all, will report back with findings.

I'm having this same issue as well with Windows 8.
HDHomeRun Dual Tuner (older model)

Have you found any further solution for this? My logs look identical to yours, and this is the last little thing I want to get working on NextPVR.
