You can change the input and output mapping on most equipment to be anything you want, provided you have the requisite skill to do so.
Your goals? Probably to get new (not old) equipment that can handle your upgraded inputs. What I'm saying is, DirecTV might have an upgraded DirecTV box for you. But you won't get anything like that upgraded unless you request it.
Moral of the story? Don't let old, broken, ugly or cheap equipment keep you down. Prioritize and you will still be gaming, online, when others fall behind. Progress can be made, you just have to know what's important and what really isn't.
Let us know if you ever get a green light to upgrade your DirecTV box.
