hi can anyone help please just set up my humax freesat hdr 500 and am missing a few channels. I can recieve bbc1 but not bbc1 hd, itv1 hd but not normal itv1, most of the movie channels, half of the music channels and few more that i probably wouldnt watch. I have tried fiddling with the satalite dish and retuning the box to no avail if anyone has any ideas please? cheers
