I thought I saw some threads on this a few months ago, but I cannot seem to find them now. My inlaws have a non-HD DVR (the 625 maybe) and are still under contract with them, but now they have a couple HDTVs so they'd like to upgrade their equipment and their package. Can they do both it at no cost? If so, what is the best way to go about getting this? Chat? Email? Call a certain number?
