Question: SONY 46EX710

46ex710 using concast xfinity. Can I or can I not use the pip feature. I like to display 2 pictures at one time, for instance, I like to watch sports on channel 6 and a movie on channel 9, and swap between the 2. Is this possible? PLEASE DO NOT GUESS, as guesses are killing me.(SO MANY FROM SO MANY. THANKS PEOPLE)
