I have had a problem with the picture breaking up and the sound freezing, where I have recorded a programme using the Tivo box. This has developed in the past six weeks or so. This sometimes also happens when watching on Amazon Prime.
I am sorry to read about the recent interruptions on the TV services, I have been looking into this and I haven't been able to find access to your connection.
I'll need some additional information and If you can have a little look inside your 'Inbox', you'll see I've sent you a 'Private Message'. You can find this at the top right of the page, purple envelope
