Hi, I was wondering if there’s a way of getting PVR functionality with a new standard Sky SD subscription, not MySky?

I was thinking either some way of connecting a PVR to the SD Sky decoder, or buying something like a Strong SRT4663X or Openbox S9 plus external hard drive and inserting the sky card into the Strong / Openbox decoder. Does anyone have any experience of whether this is likely to work, enabling recording / live pause?
