I had some that said that this recording 'will' be deleted in the next 24 hours and others that said it would be deleted in 3 days. My drive is only around 30% capacity. The only items not marked for deletion were recordings from the previous day. So some items were days old and others were over 3 years old.
I was able to mark everything as keep until I delete but I have never had this problem before. I was worried that other people could be caught out and lose all their recordings. If this is a software change by Virgin it has not been communicated very well, perhaps in the mail that looks like junk and gets filed under junk.
