I too would like COMSKIP directly supported, but I just watch all my TV shows through "Recorded TV" (otherwise like a video file). It works great, but would be better if directly supported through XBMC (Kodi).
One of the huge benefits to an HTPC is to have a PVR function that skips commercials. Got used to that with ReplayTV and always hated that I had to skip manually with my Tivo HD. But happy with the work around that lets me do it via XBMC until such time the function is directly supported by XBMC.
You "Kodi" developers, keep up the good work. You have a great system! I have not used my Tivo for several months now! Love Gotham!
