Users of TiVo and other digital video recorders are being confounded by CBS's Sunday-night primetime schedule, which often is thrown out of whack on the East Coast by overruns of sports events that begin in the afternoon, the CBS blog Public Eye observed Monday. Public Eye writer Brian Montopoli noted that coverage of the Masters Tournament Sunday pushed the start of 60 Minutes to 7:45 p.m., resulting in people who had scheduled their DVRs to record the program at its regular starting time, 7:00 p.m., seeing only 15 minutes of the program. Montopoli observed that as of the first of the year, TiVo only had about 4.4 million subscribers. "But one has to wonder how much of an impact the variable start time will have, especially as DVRs become more widespread."
