NShared.HDHomeRunRecorder threw an exception

[jhelms]

Just installed 2.5.5 and tried to configure it with my HDHomeRun, but it failed. Here's the log:

Something seems to be going wrong finding the HDHomeRun software. Do you have a HKEY_LOCAL_MACHINE\SOFTWARE\Silicondust\HDHomeRun registry key, and does it contain a InstallDir value?

[jhelms]

Yes, that key is present, and the InstallDir value is "C:\Program Files\Silicondust\HDHomeRun\". In looking at the other registry values, I also see a key called Application, and the value is "Windows Media Center". This key is also present in the individual tuner entries. Not sure if this would conflict with NPVR? Maybe I need to disable WMC?

Thanks,
John

Also are you using the 20120405 Version or a more recent Beta of the drivers? And XP or Win7 (the latest beta lost XP support)

No, the application setting shouldn't matter.

It's not entirely clear to me why you're getting this problem, but give this patch a go. It'll hopefully fix it.

[jhelms]

That did seem to fix it, but it display 6 devices for my HDHomeRun (screenshot attached). Not sure if this is per design?

Yeah, that's normal.

If you're using an HDHomeRun Prime, then use the ones of type 'HDHR'.

If you're using other HDHomeRun devices, then use either the QAM or ATSC tuner options.

[BrainStormer]

You can go to devices select the unused device, then configure, then uncheck the enable box, Then the unused ones wont show up in the show status.

[jhelms]

Well, the next problem seems to be finding channels. I tried scanning all of the various devices, but never found anything (attached). The SiliconDust software finds all of my local channels plus some ~60 miles away. Also attaching the NPVR log in zip format.
