Dunno what's missing.
Try to copy all the files from SVP 4/mpv64 into VLC's folder.
After copying into VLC's directory (i.e. the directory with the .exe) I get this error on just starting a video:
core error: option sout-deinterlace-mode does not exist
freetype error: Breaking unbreakable line
And I still get the previous error when enabling deinterlace.
