College football (5:30 p.m., ESPN): Utah at TCU
Presidential address (7 p.m., Channels 2, 4, 5, 13, CNN, FNC, MSNBC, C-SPAN): George W. Bush addresses the nation (Ch. 7 will tape-delay it at midnight), which means lots of other schedule changes.
Survivor: Guatemala (7:25 p.m., Ch. 2): Another season begins, and there are surprises right off the bat. Two contestants from past editions of "Survivor" join the 16 newbies; one of the new contestants is former NFL quarterback Gary Hogeboom; and 22-year-old Rafe Judkins (who was born in Salt Lake City, raised in Pittsburgh and lives in Providence, R.I.) describes himself as a "gay Mormon."
Joey (7:30 p.m., Ch. 5), Will & Grace (8 p.m., Ch. 5) and ER (9 p.m., Ch. 5): Last May's season finales are repeated.
The O.C. (8 p.m., Ch. 13): The new dean wants to expel Ryan and Marissa. (Delayed an hour. A repeat of the pilot of The War at Home airs at 7:30 p.m., and Reunion will be seen Friday at 8 p.m.)
Supernatural (8 p.m., Ch. 30): Tuesday's premiere is repeated.
CSI (8:25 and 9:25 p.m., Ch. 2): A pair of repeats — but not the two-hour season finale that was scheduled. That's rescheduled for Wednesday.
Scrubs (8:30 p.m., Ch. 5): Turk and Carla ask J.D. to move out. (Repeat)
PrimeTime Live (9 p.m., Ch. 4): More Katrina-aftermath coverage.
The Showbiz Show (11:30 p.m., Comedy Central): David Spade expands the snarky segment he used to do on "Saturday Night Live's" "Weekend Update" segment to a half-hour weekly show. (It's taping today, so it wasn't available for review, but I'm hopeful.)
