I got the blue spinning circle last night when I tried to access a recorded program. Live TV was OK. I made the mistake of restarting the Bolt and then I couldn't play anything - live TV or recordings. Got V117 errors - "Can't Play Now". Rebooting my router didn't seem to help. I left it for a few hours and functionality seems to be improving - Live TV is kind of working - but not normal yet.
I read another thread where I think multiple people were getting similar issues and it was attributed to some problem on TiVo's side - but I didn't expect that a back end issue could so significantly impact the box, including functionality that wouldn't seem to be dependent on them.
Between this and my Roamio only able to connect to service recently after months of errors, I'm starting to really wonder/worry about TiVo.
