Over last two been get picture/sound breaking up and pixelation, slow getting worse. Seems to happen more on SD channels than HD, but still happens on HD channels. I have rebooted the TiVo, check all the cables. Any ideas?
Sorry to hear that you have been experiencing picture breaks and pixelation on your TV service.
For this I would like to book an engineer to check this over for you. I've sent you a PM (red envelope icon, left corner) with some details for you to confirm please. Once you have replied I can go ahead with the appointment.
