DVR setup

Hi all, I have downloaded Openvix 5 1 18 and installed it on my UV+ Ultimo box, but the plugin for Plex DVR API for Enigma2
is not on the list ? I do only have 1 tuner connected at the moment as i need to run another 2 runs of coax for all 3 tuners
Can anyone please point me in the right direction please.

Thanks all.
