I am new to satellite receivers and would appreciate any help that nayone could offer me.

I have a mediastar multibox and i am using hotbird 13 degrees.

I would like to know how to upgrade the software and how to enter / edit new keys for the programmes received.

I have seen that there are many websites where you can download updated keys as zip files.

How can i enter these into the receiver with my laptop and is there any special software required.

Thanks for your help in adavnce.
