Recently the picture quality from many of my channels on my TiVo box has deteriorated, daily the picture quality alters depending on the channel.
I have experienced a lot of pixelating picture, on live, recorded and on demand channels.Also, on some channels my TiVio box is not picking them up, despite them being on air. It keeps saying 'there is a problem with signal on this channel'.
The channels that are largely affected are: BT Sport 1 and 2 HD (but not 3HD!), E4 HD, BBC 2 HD , 5HD, BBC 4HD and also some non-HD channels. In the past, Sky sports has also been affected, this channel list daily!
I have rebooted my TiVo box a few times and it keeps happening.
Please could someone advise on the next step here as it is getting very annoying!
