Doesn't Mediaportal follow this path? I don't see anything hardcoded about this in the source code. Can you tell me where it is?
There's a choice in the settings, but I don't know if you can select MPC Video Renderer there. Have you tried it by any chance? Maybe it's possible?
This is certainly good, but since MPC Video Renderer is a Direct Show Filter, maybe it would be easier to modify it so that it works in the Media Portal like LAV Filters?
Any change (no matter how it happened) in Trakt-for-Mediaportal/MPEI/TraktInstaller.xmp2 at master · Mediaportal-Plugin-Team/Trakt-for-Mediaportal will result in MPE1 being built and published.
Look...
