From YouTube:
An Update On Our View Counts
Video view counts reflect the YouTube community's interests and the grassroots popularity of videos. We periodically make changes that allow us to display consistent view counts and accurately reflect a "real" view based on video consumption, video streaming and spam filtering. Unfortunately, a few people still try to artificially manipulate their video's view counts. Some people game third-party view counts as well. That can make things unfair for everyone.
Recently, we found spamming issues associated with the view counts on a small number of videos. The inflated view count number on these videos will be frozen until actual views catch up to the published, artificial, view count. Also, a few people have commented that their view counts are updating more slowly. Occasionally the speed with which views update changes -- sometimes it’s faster and sometimes it’s slower. But we are always working to make sure that the final view count numbers are an accurate reflection of the community's interest.
