Two syndicated shows produced by Oprah Winfrey’s Harpo Studios – “Rachael Ray” and “Nate Berkus” -- have landed an exclusive cable rebroadcast window. You guessed it! They’ll both be running on Oprah’s OWN, starting Monday. “Ray,” still a broadcast success, and “Berkus,” cancelled after last season, will run in two-hour blocks each starting at 9 a.m. weekdays.
