Topic: SVP not working with MPV or SMplayer

I just downloaded SVP on a new laptop I bought and there are several issues I can't seem to fix. 

(1) I can get the RIFE engine to work with MPV if I open a video WITHIN the SVP control panel.  However, if I open a video from within MPV itself, it doesn't work.

(2) My go-to media player is SMplayer which uses the MPV "engine" to play videos.  Again, opening a video within SM player doesn't work.

Mind you, I have two other laptops with SVP installed and everything in (1) and (2) above works on those two laptops, so I'm perplexed.

Also, (3) Only the Automatic (60 fps) profile works on MPC-HC, there's a message that comes up that says if you want to run RIFE you need to install Vapoursynth.  Is that what my problem is here for all of these issues.  I'm hesitant to install vaporsynth because it blocked my usage of some Python related apps, such as Jupyter notebooks, etc., on my other two laptops in the past.

That said, I'm really confused as to why this is a problem on my new laptop and not on the other two..

Re: SVP not working with MPV or SMplayer

Vapoursynth IS already "installed" - in a _portable_ version inside SVP's install directory. If you run mpv.exe from the same directory, everything is fine.
But if you want to use Vapoursynth in 3rd-party players, you have to add it to system's PATH <---- this _can_ possibly "break" other apps using Python because of Python versions conflict.

Thanks.  My central question though is whether adding Vapoursynth to the PATH will solve my problem?  The problem I'm trying to fix is that "standalone" MPV and SMplayer do not work AT ALL right now, while MPC-HC will only run the "automatic (60fps) profile.  If adding Vapoursynth to the PATH is unlikely to fix this problem I'd rather not take the risk to "add it to the path."

More directly, forget about Vaporsynth altogether and let me simply ask, "what could be causing the standalone versions of MPV and SMplayer not to work."  MPV just ignores SVP altogether and SMplayer will simply shut down after a second or two if SVP is enabled and SMplayer is using the MPV engine.  If SMplayer is using the "Mplayer" engine the video will run but will ignore SVP.
