As far as I know, if your Sky+ is full, it will overwrite the oldest stuff that you've already viewed, unless you've marked it as keep. I've also noticed that a recording changes from Recorded to Viewed as SOON as you view it, even if you only view 1 second and exit out. So with regards to what I said in paragraph 1, does it only overwrite stuff that has been COMPLETELY viewed (i.e. all the way through), or does it overwrite ANYTHING that's marked as "Viewed" in the planner? Also does anyone know if you can manually toggle a recording between "viewed" and "recorded"?
