Hi Morgan187ann,
Welcome to the forum.
Trying to work out what you mean ref unread. Which Humax Freesat PVR do you use? If it’s a 1000/1100s model, you can’t untick/retick recordings, simply just watch them again. Or do you mean you have deleted recording and want to retrieve from recycle bin? You can’t do this, it’s permanently deleted and not accessible once deleted. Can you explain a bit more in your query and hopefully someone can help further.
