The two-hour “Dancing” earned a 5.8 among adults 18 to 49 during its second week, down a slight 9 percent from last week’s debut. The series ran over into the season finale of “What About Brian,” which posted a 3.0.

Fox was second with “Prison Break” (3.3), followed by “24” (4.7), which was up slightly from last week.

NBC had repeats of “Deal or No Deal” followed by an original “Black Donnellys” (2.3), which matched its lowest rating to date.

CBS had repeats of its comedy lineup and “CSI: Miami.” The CW had originals of its comedy block, which averaged a 1.2.
