I saw your title and we checked the channels you mentioned. Everything was working without problem.
"Some more" - is nothing, I told you. Specify particulat channels where do you have problem.
Please pay attention to the forum. Nobody else told about this issue, only you.
We may ask here the same question to other SkyLink subscribers - does anybody have any problem with channels, in particular - CT1 HD, CT2 HD and some more? and wait.
Meanwhile, check ping and route to the server when you have a problem. I think, you have to check internet connection when problem arises.
