Does the £10/month Sky+ subscription still need to be paid for PVR functionality ? And do you need to pay that for iPlayer access?
Yes, you do. It's my usual ruse to revert to this if I have to cancel at the end of a discount deal.
It means I keep the functionality of the PVR, which you need for iPlayer as it's progressive download rather than streaming on Sky. You still have access to previous recordings from the FTA/FTV channels, but not any from subscriptions channels.
You're no longer classed as a subscriber, for Sky's purposes, so you soon become eligible for another "come back to Sky" deal. (Last time it took only 3 weeks before I got another 60% off deal for 18 months)
