Q: Why does NBC show reruns of Wednesday shows on Saturdays? Don't they have any new shows for Saturday? -- Richard Desbrough, Dundee, Mich.
A: For some time now, unlike in the golden age of such weekend offerings as "The Mary Tyler Moore Show" and "The Golden Girls," the broadcast networks have considered Saturday to be a night of lower viewership that largely doesn't justify the cost of original scripted programming.
While repeats of such shows as Maria Bello's new "Prime Suspect" and "Law & Order: Special Victims Unit" have been used there by NBC lately, Saturday also has been a spot for the network to play off first-run episodes of series including "Chase" and "Outlaw." CBS is doing something similar with its freshman sitcom "How to Be a Gentleman," which it recently moved from Thursdays to Saturdays.

Q: When will we be seeing "Mike & Molly" again? Now that they have received recognition, I can't find it. -- Ruth Rogers, Menomonee Falls, Wis.
A: Though the show did miss the opening week of the current television season, it's now back on Mondays on CBS, with Melissa McCarthy -- whose recent Emmy win must be the "recognition" you're referring to -- on display again. She also was a guest host of NBC's "Saturday Night Live" earlier this month, so she's been having quite a season thus far.
