* "The X-Files" (8-9 p.m., WBFF, Channel 45) -- This is the month when the networks tinker and tweak their schedules a bit, trying out promising but low-rated shows in different time slots in hopes of building a larger audience. Later this month, NBC will throw an episode of Sunday's "seaQuest DSV" onto Thursday night. Tonight, Fox complements its normal Friday showing of "The X-Files" with a special repeat showing -- a spooky episode, guest-starring Carrie Snodgress,about a possible close encounter of the third kind. Fox.
* "Rolling Stone '93: The Year in Review" (9-10 p.m., WBFF, Channel 45) -- The good news: This isn't another typical fast-paced TV retrospective of the year's events. Instead, it takes some of pop culture's biggest 1993 newsmakers, including Steven Spielberg, k.d. lang, Jerry Seinfeld and Howard Stern, and sits them down for interviews with an unseen questioner. The bad news: The interviews are chopped up so frenetically that sometimes different camera angles are used in midsentence, and it's rare that two connected thoughts follow one another. Still, these people have interesting things to say -- especial lang, Stern, Pete Townshend and Bono, who explains that he's not being too sincere because "people prefer artifice." Fox.
* "Dateline NBC" (10-11 p.m., WMAR, Channel 2) -- One of tonight's reports is about the deterioration of tens of thousands of American bridges -- in other words, a report on troubled bridges over water. NBC.
* "NYPD Blue" (10-11 p.m., WJZ, Channel 13) -- It's Christmastime in the city, but don't expect silver bells and quiet carols. Things at the precinct are much too busy for that. ABC.
* "Divine Madness" (8-10 p.m., COM) -- Loved Bette Midler in "Gypsy" two nights ago? Here she is in a 1980 concert film, performing at her Divine Miss M best.
* "Shock Video" (9:30-10:30 p.m., HBO) -- Believe the title. There are pieces in this documentary on amateur camcorder use that, seen in succession, are one step away from sickening: police brutality, nanny brutality, muggers taping one of their own urinating on an unconscious victim, and so on. The context is sometimes lacking, but the images can be compelling, though difficult to watch.
