The last few days all three of my TiVo's (2 Bolts and 1 Roamio) been using all tuners to record 1 minute manual recordings on channel 109 and 110 (C Span & C Span 2). I have Fios. These are occurring at random times of day and using all tuners (suggestions are turned off). I discovered this because the Mini said all tuners were in use. I thought that might be possible so I changed the dvr that it was linked to and got the same message. I've been with TiVo for a long time and this is the first time this has happened. Does anyone have any idea what might be going on? Thank you.
