Phlex only partially working?



I have installed Phlex and seem to have it partially working however it will only play, stop, pause movies, there is no rewind, fast forward etc... working nor will it play anything in my TV library. A couple of other things that I have noticed is that movies always resume and there does not appear to be a way to restart a movie from the beginning, and if I repeat a command it kicks me out of the Plex client (Roku) and back to the main menu.

Am I doing something wrong or is something broken in master?
