I beleave (though not 100% sure) that once you can only use the sky+ features if you have an active sky+ subscription. meaning once your subscription ends you will no longer have access to the recorded stuffon your sky+ box. though you could downgrade your sky sub for there freesat from sky package (no running cost) and just pay the 10 p/m fee till you've watched everything.

Alternativly backup everything in your hdd to a vhd/dvd and watch them when ever you want.
