A Howard County businesswoman posted a Web video she says shows two men from Comcast Corp. ? the firm responsible for 80 percent of her business ? rummaging through her warehouse.

Celeste Wooten, owner of Wirespan Communications Inc., alleges in a $13 million lawsuit that Comcast discriminated against her company, and its employees entered her property without permission in 2004, two days before her contract as a minority supplier expired.
