We are new to XFinity, but have had DTV, Dish and FIOS. On those 3 if we are watching live TV and change the channel we could always swap/switch back to the previous channel and the buffer that was built up remains. I even remember on Dish I could pause one and when I returned to that tuner it was still paused. I have not figured out how this can be done with the X1, it has all these tuners but I can't swap between a couple of them and have the buffer remain. Any ideas, or is it not possible?
