I attempted to setup my HDhomerun extend on Nextpvr under Linux gave up. I installed Nextpvr under windows instead. I downloaded the software from the hdhomerun web siter and followed there instructions for setting it up in NextPVR https://info.hdhomerun.com/info/nextpvr I was able to complete the setup. Then I went to devices in Nextpvr. The instructions say to to scan for tuners, select the atsc tuner and click setup(step 9). But I never got a setup button. I clicked scan and it went up to channel 44 then froze up. I tried rebooting and starting over, but it imediatly goes to the same point and freezes. I even uninstalled nextpvr and it goes straight to the same point and freezes. Is there a way to clear the tuner list and start over? How is it that when I removed and re-installed Nextpvr it still showed my tuner without having to scan for tuners? Is there a config file that does not delete when I remove and reinstall Nextpvr? Setting up my Wintv QuadHD usb was a breeze. I'm on the verge of smashing this HDHomeC**p. It seems to work fine with the Hdhomerun dvr.
