No, my memory isn't that bad but with a few in the family all recording their own stuff, the box is filling up fast. I've read the manual, the updated manual online and google'd this question but no luck so far (or my glasses need replacing). Is there an on-screen indicator to show that a program has been watched when viewing the media list? If there is, then the family can be told what to look for when searching for something to delete to free up some space. Delete it having watched it isn't always an option, others might want to watch it which just makes the delete option even more fun.
