If you got Directv to give you the box, installer coming out to hook it up, it would be installed.So they would have to come back out or is that something I can purchase and do myself?
If you got your box say at Best Buy, I don't think they are included in those yet, so most likely you would have to purchase one.
Possibly Directv could send you one out, I'm not completely sure on this one, maybe Stonecold could help out.
When the time comes, if you have any issues, just PM me, I'll help you out.
