I tried in HereSphere this morning and it worked. Used the IVDB.IO funscript download file just like any other (locate in same directory and same name as video) and it simply just works, easy as could be. I did not try DEOVR or Pigasus, but these appear to work as well based on this article IVDB Local Video Sync – Handy Setup. If future wonderers find this post I recommend trying these players instead of integrating a script player with a video player. The one stop shop is also nice, i.e. being able to adjust script settings and video settings from one application. Note that the IVDB.IO download files are tokens, essentially a key to funscript data, and the applications you use need to know how to work with that. Thanks again Charz for the initial response.
