George the good news its easily sorted, the type of dish fitted is of no issue, if you still have reception of the the other channels then no dish adjustment. Channels do move frequency, there is usually a warning several days prior which pops up saying channel is moving on this date so retune,it usually says where its going. My receiver does both manual and auto tune i prefer manual as an auto can sometimes cause havoc with other channels. Mr google will normally tell you where to find the channel, receivers are all a bit different but again just google yours and there should be a pdf booklet or a you tube video. Alternatively the nice Mr diginova will sort it out every few months, its not his fault the channels move so i suppose nothings free.
