The episode, that is not solely about conditions in Sacramento, is scheduled to be aired next week.
A publicist for Winfrey's production company is quoted saying, "We're going to be showing viewers the real face of the recession."
Besides Loaves & Fishes, the article tells us "[the film] crew also looked at the Mustard Seed School, Volunteers of American, the 100-tent homeless encampment [known as the Wasteland] and the St. John's Women's Shelter."
Bee's 21Q blog promises to give us the air date of the episode that will include Sacramento scenes when it is scheduled.
UPDATE 2/20/09: The Bee now tells us the "upcoming episode of 'The Oprah Winfrey Show' will feature a family that was left homeless in Sacramento after the short sale of their home." It is perhaps/probably the case that the broader story of homelessness in Sacramento was not of interest to Oprah/Harpo Productions. [FYI: Sched of upcoming shows at oprah.com. ]
UPDATE 2/24/09: Note that we now know that Oprah, herself, DID NOT come to Sacramento. Lisa Ling and an "Oprah" film crew were here on Feb 11, 12 & 13.
