Limited Functionality watching Yahoo! Video with Opera 9–
Yahoo delivers video formatted in Window Media, Flash, and QuickTime. The majority of our content is formatted in Windows Media. For content formatted in Flash or QuickTime, all video playback functionality is supported. However, Opera (and all Mozilla-based browsers) do not support the Active X scripts needed to control video playback. Therefore, the video player controls (pause, fast forward, and stop) are disabled for videos formatted in Windows Media using the Opera browser.
Yahoo will continue to work to improve the video experience using the Opera browser.
