NRecord crashing with last message “FindFilterByName failed to locate filter: NPVR Net Push Source”

Attached are two logs and two sets of Windows Event Log entries.

On 11 May there was to be two recordings at 1700 and two recordings at 1730. NRecord crashed at 1700. I restarted NRecord at 1751 and the two 1730 recordings started without error. Although there is no log entries for FindFilterByName success, all of the successful recordings have a message “Removing filter NPVR Net Push Source”

I had suspected that Bitdefender AV+ was involved somehow but there is no events in the Windows Event Log or events in Bitdefender that it has been involved.

Last time you reported a problem it was this same thing, and we talked you through re-registering it. Now that component has unregistered itself again. I'm sure it's going to be somehow antivirus related. The app is not going to work without 'NPVR Net Push Source', so you've got to somehow stop your antivirus messing with it.

As I understand your analysis of this problem: Bitdefender is modifying registry entries/data. Thus causing the failure: FindFilterByName failed to locate filter: NPVR Net Push Source. And that the ONLY way to reestablish these entries is (re) executing regsvr32 "c:\program files (x86)\NPVR\NPVRNetPushSource.ax"

Correct me if I am wrong here but my assumption is that if there is no registry entry for Net Push Source, it would be impossible for NRecord to make ANY recordings.

If the above is true, I have to repeat my previous question: On 11 May there was to be two recordings at 1700 and two recordings at 1730. NRecord crashed at 1700. I restarted NRecord at 1751 and the two 1730 recordings started without error. Although there is no log entries for FindFilterByName success, on completion all of the successful recordings have a message “Removing filter NPVR Net Push Source” I did NOT execute regsvr32 "c:\program files (x86)\NPVR\NPVRNetPushSource.ax" in between the crash and restarting NRecord. How is that NRecord can now correctly record 13 programs ?

Either way you have to get that directshow filter registered, and make it stay registered. Because there is no other users reporting problems with it not being registered, then I'm pretty sure its something specific to the software on your system that is blocking access to it (even if inconsistently so).
