TV highlights: Oprah interviews Lindsay Lohan

Farewell, Speed channel -- as of Saturday morning, Fox Sports 1 launches in its place, focusing on college sports, NASCAR and UFC. Also, goodbye to "Do No Harm" (NBC at 10 p.m.), the Jekyll-and-Hyde medical series that was pulled off the weekday prime-time schedule almost immediately. In the series finale, Jason panics when his alter ego, Ian, unexpectedly starts taking over his body during his day job.
