I don't know anything about Rochester but I'm flying Jet Blue out of Washington Dulles on Sunday myself - used a $25 voucher they gave out the last time I flew them, and half the TV channels didn't work, so they gave everybody a voucher. If my TV doesn't work, I'm going to ask about vouchers, then get out my Ipod.
You must pay for movies, but you can watch television for no extra cost. They have satellite TV in the back of every seat. Lots of channels. I will have Food Network on for a couple of hours, no doubt. Jet Blue also has a choice of really good snacks, and you can ask for more if they have any left to give you.
I don't think "early boarding" means you will board before disabled boarding or anything like that. It just means you will be in one of the first groups to board.
