Several cases have been reported that antivirus like kaspersky and Mcafee are blocking streaming contents and due to this problem you can only view videos after fully downloading the entire video. To confirm whether Kaspersky actually blocks streaming videos, temporarily disable the antivirus and try playing the video. If youtube video plays without any problem then you can be sure that kaspersky is causing this problem.
