Having just got Sky+ there is one feature that puzzles and troubles me slightly - that feature being Instant Rewind, and yes I know the topic has been covered before but I would appreciate some clarification. I am right in assuming that IR records a set amount (user controlled) of whatever channel the Sky+ box is tuned to in a buffer? Is that from the start of every programme or just from the time the digi box was tuned to that particular channel? If it is doing this then is it not going to be very wearing on the Hard Drive to have it constantly spinning and recording. For the time being I have turned mine of until this issue has been cleared up to my satisfaction.
