I recently received a message from Xfinity that it was time to upgrade my cable box. I box I was sent is the same model as the old box - XG2v2. The only difference is that the old box had a -S suffix (Samsung) and the "new" box has a -P suffix (Pace). There seems to be no difference in the performance, so what was the point of swapping out the equipment? Does the Pace box do something that the Samsung box does not?
