*Tuesday night’s two-hour premiere of Paula Abdul’s CBS competition reality show “Live to Dance” (8-10 p.m.) attracted the most total viewers (10.2 million), holding its own compared to the premiere of NBC’s “Biggest Loser Couples.”

However, the NBC weight loss staple took the block among the ad-centric 18-49 demographic (3.3 versus 2.4 for Dance), according to the Hollywood Reporter.

At 8 p.m., ABC’s No Ordinary Family (1.9, 6.7 million) was flat compared to its last original episode on Dec. 7. But the second series premiere of ABC’s V at 9 p.m. was down a whopping 60% compared to its last premiere in November 2009 managing a 2.1 with 6.5 million viewers.

Fox was fourth at 8 and 9 p.m. with a rerun of Glee (1.7, 4.7 million) and Million Dollar Money Drop (1.3, 3.7 million). And the CW barely registered a pulse with reruns of One Tree Hill (0.4, 1.0 million) and Life Unexpected (0.3, 827,000).

At 10 p.m., NBC’s Parenthood won the hour in the demo (2.3), up 21% compared to its last original in November delivering its largest total audience (6.0 million) since September. But a rerun of NCIS (1.7, 10. 2 million) was tops in the hour among total viewers.

ABC’s Detroit 1-8-7 (1.2, 5.1 million) sunk to its lowest-rated telecast ever dropping 14% compared to its last original on Dec. 7.
