I've been transferring shows from my pc's to my Tivo's for many years with no problem. As of yesterday, I'm unable to do so. Usually I use bonjour because it's quicker, but the bonjour connection doesn't even show up in the Roamio so I switched to "tivo beacon" and the tv sees the pc's but says the now playing list is unavailable. This is literally out of the blue - everything was fine until yesterday. I'm guessing there was an update installed. I'm using the "old" Tivo interface, not Hydra.
