A Google search turns up a web site maintained by this woman, with a video she has put up of her life story, and another of her appearance on a religion-themed talk show. On these videos, she reveals that her mother miscarried a boy child before she was born, that her parents had always desperately wanted a male child, and that they exerted intense unspoken pressure on her to be male throughout her early childhood. She includes none of this information in the video of her testimony before the California legislature.
Because it appears that her cross-gender feelings originated with her parents' desire for a boy instead of originating within her, the complete version of her life story--far from demonstrating that transsexuality and homosexuality are choices--looks more like evidence that gender identity and sexual orientation are immutable: They tried to impose a male identity on her. It failed.
