Exception in Loop: Object reference not set to an instance of object

If you need anything more, please feel free to ask. The 2012 server seems to be locked down much more than 2008, so maybe something that normally had rights is now not available.

Can you please tell me which templates / presets you use for your cameras?

I would really like to be able to reproduce this problem but so far it’s nothing that I could suspect and didn’t find a way to reproduce it…

I’m using just 2 types:
Mostly DLink-920 mjpeg
About 3 Eminent 4482 mjpeg (on Chinese no-name cameras, since Webcam XP…)

Just about to swap to some Dlink 930L cameras where some of the older ones have failed.

By the way, I tested what happens if I select record on each type of camera, 1 only. In fast record, the exception comes immediately on initiate recording.
Something that I noticed before, and happened again tonight when I added a source: some, not all, of the source names get out of synchronization, and I need to “edit video source” and re-save without changing anything. I mention it just in case it might be related.
Happy hunting!
