Some of the HD channels on my TT box seem to be missing. I have seen the thread titled 'Loss of Channels from 22nd June' so this may be the answer to my query. However I would welcome any comments about the following.
The only HD channels showing in my channel list are 101 to 105. The next channel listed is 201. I don't regularly watch HD but I seem to remember having many more available.
Thanks for your reply. I have followed your advice and re-tuned my box. Before re-tune I had 133 TV aerial channels and 77 subscription channels. Afterwards there were 163 and 77, 20 more TV aerial channels. None of the additions appeared in the range of channels 106 to 200.
I am not one for demanding the extra quality of HD so usually watch the regular digital channels. I can't remember which HD channels were previously available but now gone.
