Looks like they are considering this business model,presumably to complete with NTL and Telewest's forthcoming PVR......
If NTL's PVR turns out to be free, then it might be worthwhile to existing Sky+ subscribers to drop to the freeview only and get NTL PVR. That way they will have x2 PVRs.....
Not quite sure which forum to post this in btw....
