A bit of a tale but my Sky + was not dual recording, as it was running an older software version. I rang Sky & they talked me through, forcing it to upgrade. For info as follows - Unplug box Remove viewing card Press & hold back up button on box Whilst pressing back up, plug back in & wait for all the lights on the front to light. Tv displays message upgrade in progress, don't unplug etc Release back up & wait When finished ower up, re-insert viewing card Simple when you know how. I think most boxes will have upgraded automaticaly, but if yours hasn't you know what to do.
