PVRs and DVD recorders are illegal?
Come on BOAC, you're clutching at straws here.
You know very well, I'm sure, that PVRs and DVD recorders are the modern day VHS.
The Copyright, Designs and Patents Act permits the domestic recording of broadcasts for what is known as timeshifting.
However iPlayer is already a timeshifted service, and it is certainly not a broadcast (however, a TV license
IS required if you want to use the simulcast feature of iPlayer).
