Add DVR Schedule as a source

[dmxking512]

I've got a HD-HomeRun setup with my plex so that i can record and watch broadcast TV.

I appreciate its quite the task but it would be cool if one of the places overseer could get the media from would be by scheduling a DVR recording. instead of cough acquiring the episodes / films from other locations

e.g Someone requested Family Guy - that's shown on ITV in the evenings, lets set a DVR schedule for it.
