I just ordered a Roamio which I will use to replace my Premier. Anyone know how to minimize the hassle of getting Comcast to switch my cable card to the new Roamio when it arrives? Should I call the cable card number before moving the card, or can I move it, then call Comcast? Any list of data I'll need to gather before I call to minimize the time on the phone? (I make this move because the Premier really did start working correctly when Comcast pushed the new firmware, so I have slightly greater confidence that a Roamio will work, and I really like the idea of the user interface being faster).
