Recording's won't start - Invalid files passed

[Vitenka]

Logs attached - reording doens't seem to work. Latest 3.4.8, downloaded today.
The directory I am trying to save to is z:\shared videos\ and it does exist; but npvr isn't creating files inside of it.
I'm able to watch live TV just fine - but not record.

The important snippets seem to be (nrecord):

Looks like it thinks it isn't locked. No idea why though, since it works ok when viewing live (with the same 'locked' result)
This symptom (no lock reported) seems very similar to the one I reported at http://forums.nextpvr.com/showthread.php...-channels& but here I can view live just fine.
Can only receive some channels which we never actually got to the bottom of.

the invalid file message isn't the problem, but it's probably a symptom of the same underlying problem: it's probably a permissions issue and nrecord/ndigitalhost can't create a file in that directory. is z: a network location? the NRecord service runs using the Local System account, so you need to grant 'everyone' permissions not just your regular user account.

[sub]

The recording service runs as a different user account, so wont see any drive mappings you've made. You'd either need to change the recording service to run as your account, or change the recording directory to a UNC path (ie \\server\share).

[Vitenka]

That probably is it; changing to a location on the local hard drive allows it to work.

Is there nothing I can do to have it run in my own context?

Also, as a bug - I selected the save location through the settings menu; why did it allow me to select a location it cannot actually use? Or at least not give a useful error message when it tried to save and failed?

Anyway; I think that it has full access now:
Z:\>cacls "Shared Videos"
Z:\Shared Videos <Account Domain not found>F
<Account Domain not found>F
Everyone:F
(and I restarted the recording service, in case that was needed)
No luck. No recording, same error in log:
2015-08-20 22:46:41.757 [DEBUG][5] File size is 0 bytes (non-existant)

So I'm now very stuck - leaving aside that it was a PITA to get this NAS to work at all and reconfiguring it is likely to give me migraines and that I really don't like the idea of having to leave the barn door open so that npvr can save if that really is the option I need.

in services.msc you can change NPVR Recording Service so that it uses your local user account.

there's also a network drive mapping utility available on here somewhere, I think mvallevand wrote it, that can make mapped drives work with the system account.

Also tried using UNC path:
<RecordingDirectory>\\192.168.8.4\Public\Shared Videos</RecordingDirectory>
No change.

Aha, just saw your reply - will try those.

No joy to either of those. Given that I can record to local drvie that would seem to provide a workaruond though - I'll try using a postprocessing.bat to move it to the right location.

You did something wrong if sharehelper doesn't work. Upload your NREcord and Sharehlep log and I can check.

that was it, sharehelper. I couldn't think of the name, glad you were scanning the forums too. I did go look on the wiki, thought maybe it'd be listed in the Utilities section.
