Here is another video player software.
YouPlayer is a video player with playlist similar to the one in Winamp. You may add/drag a YouTube, Google Video, Metacafe or MySpace link into a playlist window. When you double-click on it, it will be shown in the video window. You may drag a link to a browser window or right-click it and open in a new tab. You may also add/drag other links, thus the playlist will work as a bookmarker. YouPlayer also allows you to download video files! Just right-click it on the playlist and select 'download'.
