To pull anything in from the Lyngsat list for 19.2East, you will need to swing your dish round to that satellite, its also advisable to pick a frequency that has a viewable channel on it, not interactive or encrypted). I'm presuming that you haven't done that yet. If you have, then you need to go into the installers menu, Services/System Setup/01select/Manual Tuning and enter the transponder into that menu, it will then give you a signal strength and quality reading that you can use to tune the dish to the satellite.
It is worth mentioning (and perhaps should have been mentioned before) that it can prove to be either be very easy, or take a considerable amount of time to do this using only the Digibox. Some people have done the job in seconds and others spend a whole weekend, only to have to give up and spend £50 on a local installer to re-align the dish back to the Sky digital satellite.
You also ideally need to be able to see what is happening on the TV screen while you are s-l-o-w-l-y moving the dish.
