Dude - You may want to start by reading what FTA is all about and then you'll have a clear picture of what is done around here. Kind of hard to answer your question since we don't know what you are trying to do.
if you wish to upgrade with dn and pay extra for it then you need to call dn,on the other hand if you want to buy an fta receiver and enjoy free tv,then please post here so we can help you
