Whenever I press the Red button on BT Sport and then exit, Tivo becomes unusable. The picture freezes and rapidly flickers, although the sound plays as normal. There is nothing I can do to recover the situation - however if I go to the home screen the mini preview screen in the top right plays video and audio as normal for some reason.
The only way to recover is to reboot the box. I don't use BT Sport Red Button intentionally but sometimes it's easy to accidentally press the Red Button and going through this rigmarole every time is tiresome
Is there anything I can try bar replacing the box?

I've run some checks from this end and can't see any obvious issues. I'm going to send you a private message to ask a few questions, so please look to the top right of this page where you'll see a purple envelope icon, click on this and you'll see my message.
