my Tivo box is fine when watching live TV, but when watching recordings they freeze and pixelate. It has been doing it on and off for a few weeks but its now getting worse. Everything i record freezes at points when watching back.
i restarted everything today but it didnt make a difference.
Thank you for your post and welcome to the Community
I'm sorry to read about the recordings playing up here, at first glance this seems like a Hard drive issue.
I've had a look and to my suspicion, the Hard drive is showing some errors on sectors. This would require a box swap most likely if there's a fault with the hardware.
I would like to arrange a visit and I've sent you a 'Private Message', you can find this by clicking on the little blue envelope near the top right of the page. With this in mind and they decide to swap, you will need to watch all of your shows as there's no current way to swap shows too.
