Hi, I recently bought the cheapest satellite receiver from Maplin to replace my in-laws' 5 year old receiver which had broken down. The Maplin receiver works fine, but there are certain channels they can no longer see because they appear "scrambled". For example RAI 4. The previous receiver had no special subscription cards or decoder cards anything else but somehow managed to show those channels. Can someone please let me know how this is supposed to work? Do we need to buy a different receiver and which one? Thanks
