我做的网页中那个视频的位置不固定。当鼠标的中间滚轮上下滑动的时候视频就会上下的跳动。网站中插入视频的代码如下
            <object id="NSPlay"
            codebase="http://activex.,4,5,715"
            type="application/x-oleobject" height="365" hspace="0"
            standby="Loading Microsoft Windows Media Player components"
            width="455" align="center"
            classid="CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95">
                <param name="AutoRewind" value="1" />
                <param name="FileName" value="images/index.wmv" />
                <param name="ShowTracker" value="1" />
                <param name="ShowDisplay" value="0" />
                <param name="ShowCaptioning" value="0" />
                <param name="AutoStart" value="1" />
                <embed src="1" width="456" height="367" hspace="0" autostart="0" align="center" autorewind="0" filename="chazhen.wmv" showtracker="1" showdisplay="0" showcaptioning="0"></embed>
                <!-- ASX File Name -->
                <!-- Display Tracker Controls -->
                <!-- Show
            Display -->
                <!-- Player Autostart -->
              </object>

我先把这个视频固定住，不让它上下的跳动。怎么能做到？请大家帮忙，小弟很着急，在线等。
