I am in the Boston market and given the update re: On Demand I am considering upgrading from my series 3 HD to the Premiere XL4. I did have a question. I remember having a terrible time getting the cable card up and running and paired with Comcast way back when I first got the HD. With the XL4 is it simply a matter of removing the cable card from the HD and plugging it into the XL4, or do you have to go through a whole set up process again? Thanks for any help/advice!
