Tvheadend

Hi
i am trying to set up CCcam with tvheadend
and i think i have it all setup correctly but i am not sure if clines that i am using work
i only need Sky UK and it would seem that most suppliers of clines are having problems with Sky UK
and more so With the HD . so what i would like to know is there anyone on this forum using Clines with Sky UK and if who are you using and does it work ?
thanks
