Since XySubFilter is based on VSFilter (which is for some user slow) I present an alternative called AssFilterMod to render subtitles. It's based on libass which is also easier for developers to contribute/code because VSFilter is still a mess. The rendering times should be theoretically lower compared to MPC-HCs own VSFilter. All the complex stuff is in an external library (libass) that he doesn't need to worry about. The AssFilterMod filter is just a wrapper for libass. So it is a relatively small amount of code to maintain. Installation: Extract the .zip and register the .dll file with the given bat file (admin privs).
