I've got 2 Tivo Bolt's. Whenever I try to use the apps (NetFlix, Hulu, Amazon Prime), it freezes/locks the entire Tivo. Reboot and then it'll work fine *for that app*. Try a different app and same thing. I don't recall having this issue until Tivo introduced the pre-show ads and/or Tivo +. Anyone else having this issue? And short of using a Roku/Fire device, any fix/workaround for this?
