At the Scripps Networks upfront presentation to advertisers Wednesday in Manhattan, Food Network talked about turning up the heat after its most-watched year yet; HGTV focused on shows starring cute carpenter Carter Oosterhouse and other experts in the home and garden arenas; DIY Network raised its celebrity quotient with a special starring “The Tonight Show” host Jay Leno and his cars; and Fine Living TV Network promised to help viewers do more with their time and money.

Food Network’s new slate includes “The Next Iron Chef of America” and “Food Dudes,” the latter featuring two Hollywood hipster caterers who look more like slackers than the skilled chefs they are. Also debuting in the 2007 season: a road trip to “Diners, Drive-ins & Dives” around the country; the Hispanic-flavored “Simply Delicioso”; and the first “Foot Network Awards” coming April 15.

HGTV will follow “Property Virgins,” otherwise known as first-time homebuyers; and watch adult children get the boot from their parents in “Guess What? You’re Moving Out.”

Mr. Oosterhouse helps homeowners confronting renovations in “Carter Can” (working title) and shows what happens behind “Carter’s” team in a companion show for DIY Network.

Vern Yip returns as the host of “HGTV Design Star” and “Deserving Design,” in which he makes over two rooms for people.

DIY will add more than 400 hours of original programming. Among them: “Celebrity Rides,” a one-hour special that will take viewers into car collector Leno’s garage for a look at his Duesenbergs and his four full-time mechanics; limited series “Project Treehouse”; and “Sweat Equity,” which shows homeowners how to increase the value of their home by $10,000 in two weekends of DIY’ing.

Fine Living’s lineup includes “Mail Order Makeover,” on which competing designers order furniture and accessories from catalogs to try to please homeowners, who get to keep the goods from the winning room; “What’s Your Time Worth?,” about when it may pay to hire someone to do some chores; and “Shopping Detective,” billed as the ultimate buyers’ guide show.
