I received a new TiVo 1Tb box just over a month ago after the old box started freezing and pixellating. At first all was well but after the box was was updated it has gone on a go-slow. Whilst watching live TV if I check the planner I lose 5 to 10 seconds of the live programme, before the planner screen appears.Try to watch something from the planner and there's nearly time to make a cup of tea! NOT GOOD ENOUGH!!! If it is meant to be an upgrade it should be better, not worse.I have even been checking out Sky Q boxes. Do something or you may lose a customer.
There is a workaround for this go to the home button then help and settings menu then clear or reset tivo box then clear thumb ratings and suggestions . Pop your pin in and enter 3 thumbs down and itll delete the thumb ratings but not your recorded programs and this will speed tje box back up .
Its all to do with the latest software update this is a workaround until a newer version is ready to be delivered by software download to the box
