You have to mark the right media type in Plex. "Movies" and "TV" will match against specific regexes, otherwise they won't show up. "Home Videos" will match everything. I host my home videos via Plex and it works fine. I also host a Downloads folder as media type "Home Videos" for miscellaneous videos because this is the only way to get it to match everything. With XBMC, you used to be able to go back into the library settings and add/change the regexes yourself (was useful on shows like Avatar that would call seasons "books"). I wasn't able to figure out how to do this with Plex.
