Time Warner Cable is offering its customers the ability to “rewind” shows. “With Start Over, digital cable customers who miss the beginning of certain shows, but who tune in before the end, can push a button and go back to the start. They also can pause and rewind the show — but can’t fast-forward through commercials. The service lets viewers act on impulse or because of unexpected delays. They don’t have to plan ahead to record a show, as they do with digital video recorders.”
