Unbelievable, it worked. God bless you
I copied the folder 2 times so I had mpv64,mpv642,mpv643 folders. I added the 2 new folders to the "Path" directory and changed the exes to mpv2.exe and mpv3.exe
I also added mpvpipe2, mpvpipe3 in the conf files and in SVP. And I added the paths in SVP to the mpv2.exe and mpv3.exe
And I think the multiple value needed to be changed. Its at 8 now. With 0 or 2 it didnt really work properly?!
Anyway it works now SVP Pro is a goddamn nice tool god bless you all And the MPV is usually smoother and better to handle than MPC-HC so its nice that works now with multiple instances.
