According to the study, ratings increase just over 15% due to DVR playback from live to live-plus-seven. The average rating against adults aged 18-49 was 2.5 for live viewing and 2.9 for live-plus-seven viewing; an increase of only 16.7%. While fast-forwarding through the ads is still an issue, not all people who use a DVR fast-forward. The data show that less than half of people who watch a recorded program fast-forward through the ads during playback. Equally significant, the top 10 most-DVR'd primetime shows among adults 18-49 experience as much as 58% of playback on the same day (CBS's Survivor: China) and as little as 27%.
