ON AND OFF THE AIR:
* "Trek" alert! While you won't notice it immediately because the series is in repeats, WBFF-Channel 45 tonight makes ,,TC mid-course correction in the scheduling of "Star Trek: The Next Generation," which adds yet one more viewing to the weekly schedule.
Now, new episodes of the syndicated series will premiere each week on Wednesday at 9 p.m., with that episode repeating at 6 p.m. Sunday. Previously, Sunday at 6 was the first-run premiere time on Channel 45, with a Saturday at 6 p.m. repeat. (That Saturday slot now will feature a different episode from previous seasons of the show starring Patrick Stewart as Capt. Jean Luc Picard of the starship Enterprise.)
The change means the first new "Trek" sighting each week now comes ahead of the 6 p.m. Saturday first-run airing on Washington's WDCA-Channel 20. It also means Wednesday offers back-to-back voyages where no man has gone before on Channel 45, at 9 and 10 p.m.
* For Baltimore area cable subscribers, by the way, "Star Trek: The Next Generation" now seems the show you can watch most often in a single week, because the local cable systems all carry Channel 20, which also carries the quality sci-fi series.
Media Monitor counts no less than 16 airings of the show weekly on the two stations, with nine on 45 and seven on 20. Many of the air times overlap, but often the episodes are different. So frequently "Trek" fans may choose between two plots, and, if properly VCR-equipped (with an "A/B switch" to kick out of cable) can tape the one they don't watch.
On Saturdays and Sundays, both stations have the show at 6 p.m., with Channel 45 also airing an episode at 10 p.m. Saturdays. And Monday through Friday, both screen episodes at 10 p.m., with the new Wednesday airing also starting tonight on 45.
* While we were counting "Treks," we also noticed a couple of other shows can be seen multiple times at least one day of the week: "The Cosby Show" and "Cheers."
On Thursdays, both can be seen no less than four times by cable subscribers whose systems carry Washington's Channel 20 and WTTG-Channel 5, plus New York superstation WOR (as most local systems do).
"Cosby" reruns are on at 5 p.m. on WJZ-Channel 13, 6 p.m. on WOR and 7 p.m. on Channel 5, with new NBC episodes, of course, at 8 p.m. (Channel 2).
"Cheers" repeats are at 7:30 and 11 p.m. on Channel 20, and at 12:30 a.m. on WMAR-Channel 2, with new NBC episodes at 9 p.m. (Channel 2).
* Here's a blast from the pop music past: Tonight's episode of NBC's "Quantum Leap" (at 10, Channel 2), includes a guest shot by Peter Noone. Do you remember him? He was the lead singer of the '60s/'70s rock group Herman's Hermits.
