What we're watching: CBS has made a slight lineup change, moving How I Met Your Mother ahead of not-cancelled-yet The Class. What About Brian is back on ABC with its second season premiere, which would give us a peek at what Monday night will bring all fall, except for The CW switching its Sunday and Monday shows starting next week. We always know when Monday Night Fotball is coming on and tonight the Baltimore Ravens take on the Denver Broncos in what should be an excellent matchup.

Our traditional high-def listings continue below.
