Mostly just simple playback. Taking the media path and of it can just playing it directly. and a really basic if path contains xyz remove it, and replace with \\abc.
I'm ignoring the transcoding and most of the advanced plex features.

My plex plugin is pretty much done, just doing the new user stuff etc.
