How to make Plex forget about my Tuners

As part of my move to get all 6 of my HDHomeRun Dual tuners working with the three separate devices I have, I backed down to 1.6.1.3722. I also removed my HDHomeRun Dual devices and started completely over with the DVR setup. However, for some odd reason, Plex detects 6 devices (2 of each of the three IP addresses assigned). Even after I add the three devices, it still shows three more, which seems very wrong.

I’m also getting errors in the Plex Media Server log stating “MediaSub: There was no scheduler for the DVR.” and shows don’t record.

Somethings very messed up, and I’m not sure how to lobotomize everything Plex thinks it knows about my DVR setup, but without doing so, things aren’t recording right at all now. :’(
