Hello everyone.Im new to this and really could do with some help.Can anyone please tell me how to pickup the freesat "red button" HD channels i.e. C4HD, E4HD, ITVHD on a Tecnomate 6800 HD reciever. I can pickup BBCHD with excellent results but this is obviously a dedicated HD channel and can be put into the channel listings. There seems to be no "red button" option on the machine and I really am stumped . Any help would be very much apprecieted .
