How boring is broadcast TV tonight? So boring that the only thing worth listing, much less watching, is the premiere of Fox's preseason NFL coverage. Cable, though, is well-stocked with alternatives.
* "NFL Football" (8 p.m.-conclusion, WBFF, Channel 45) -- John Madden and Pat Summerall are used to working together on the road, but beginning tonight they're heading in a new direction on an uncharted highway. This exhibition game between the Denver Broncos and the San Francisco 49ers may not be very important -- but as an exhibition of how Fox covers football, it's the most intriguing TV offering of the evening. Fox.
* "Max Headroom" (8 p.m.-9 p.m., Bravo) -- This series wraps up its Bravo replay with "Baby Grobags," an episode never seen on ABC because the network canceled this 1987 series before showing this finale. Matt Frewer stars as both Max Headroom and Edison Carter, and seeing a fresh "Max" seven years later is quite a time trip. It's also a jolt to catch Jeffrey Tambor, now of "The Larry Sanders Show," featured as Edison's assistant.
* "Woodstock '94 Preview" (8 p.m.-10 p.m., MTV) -- When Van Morrison sang, on the 1971 "Tupelo Honey" album, of going down to "old, old Woodstock," he probably never envisioned this: a 25th-anniversary attempt to recapture the spirit, and reconfigure the borders, of Woodstock Nation. Tonight the preview chores belong to MTV, which will provide updates and cut-ins all weekend -- but the main action will be tomorrow and Sunday and will be available chiefly on pay-per-view. At least, that is, until the release of the CD and video.
* "Are You Lonesome Tonight?" (9 p.m.-11 p.m., USA) -- You have to be desperate tonight, not just lonesome, to sit through what the USA Network has in store: a marathon of Jane Seymour movies, most of them made for TV. This dumb 1992 mystery starts it off (and is watchable only for Beth Broderick's phone-sex operator), followed by 1985's "Obsessed With a Married Woman" at 11 p.m., 1990's "Matters of the Heart" at 1 a.m., and 1980's "Somewhere in Time" (a theatrical film) at 3.
* "Runaway Daughters" (10 p.m.-11:25 p.m., Showtime) -- Joe Dante directs this "Rebel Highway" made-for-tv movie, and he and writer Charlie Haas give it a lighter touch than most entries in this series. Watch for cameos by Roger Corman, the spiritual father of this B-movie salute, and also by Fabian, Joe Flaherty and Robert Picardo.
