If the recordings are from FTA channels and you're technically inclined it's perfectly possible to remove the hard drive and extract the content to a PC as a bunch of transport stream files. Recordings from encrypted channels will remain encrypted (they are decrypted on replay)

exPVR is worth a google. I think it copes with the old SD Sky+ drive format, if not then Copy+ might also be worth a look.
