So, do you have two boxes, or just one?
And if it's two boxes are they both boxes with hard disks (converted V6 boxes) or one box with a hard disk and a mini-box?
The message suggests that the recording is on the other box, either because you only have one box with a hard disk or because the program was set to record on the other box and that box is not responding (because it is switched off or doesn't have a network connection).
