As some others have probably realised, some of the FTA HD channels that got paired a while back are now back in sharing and also clearing with a basic viewing card inserted in the original receiver
The past few days these have all been clearing
ITV2 HD
ITV3 HD
ITV4 HD
Encore HD
There has been nothing official on this (for obvious reasons), but it could be speculated that the ITV are concerned that they will lose revenue from potential advertisers who are no longer reaching the larger FTA market
Good news indeed for us all, let's hope this is not just a temporary thing and they are back with us for good
