Best NVR to use, open to all brands?

For the NVR, as pointed out in the other thread you are in, SmartPSS lite works just fine. Not sure why yours is messed up.

Maybe see if you can find an older SmartPSS program?
That's sort of the point. The smartPSS is having the same issue as using the webplugin,. No video. If I use edge to see it, there is no editing function. Anyway That's the way it is. I will drop it here.
