I have a 4-tuner Roamio, that can be used with either cable or OTA. It does not have a subscription, since I used the $99 summer sale to transfer lifetime to a new Bolt. I tried selling the Roamio on Facebook Marketplace, but FB blocked it, saying it violated marketplace rules or something. Don't understand why, and I didn't really get an explanation. I haven't tried selling it elsewhere yet, but figured it would be good for a cord-cutter who might want a DVR with an OTA antenna (but with an option to use with cable too). Anyone else try posting one to the Marketplace and have a similar issue?
