From build 5.0.015 a new plugin is available and is coded for use with Plex DVR
This will allow you to use Plex's DVR system to record shows from your E2 box directly into your Plex library. The EPG system in Plex is powered by Gracenote.
PlexDVR is ONLY available to PLEX PASS members at the moment and you must use version 1.7.0 or above

I have attached a quick setup guide.
