Quoting Tony Grant (tony@tgds.net):
1. How do I view "Free to view" scrambled channels?
What does "free to view" mean?
ITV1 and Channel 4 on Astra 28.2 E
No, they are part of the SkyDigital package. Some of the channels they
broadcast (like ITV News Channel on 12032 H) are offered free to air,
but channel 4 and ITV are encrypted, and thus require the CI-CAM and a
subscription to SkyDigital.
That's almost true. ITV1, Channel 4 and Channel 5 are encrypted, but
they can be viewed by using a so-called "free-to-view" viewing card.
