视频点播路径连接问题

弄了一个简单的视频点播，代码如下，
1.aspx:
<object classid="clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA" class="OBJECT" id="RAOCX" width="500" height="350">
        <param name="_ExtentX" value="9843">
        <param name="_ExtentY" value="7620">
        <param name="AUTOSTART" value="-1">
        <param name="SHUFFLE" value="0">
        <param name="PREFETCH" value="0">
        <param name="NOLABELS" value="0">
        <param name="SRC" value="<%=Session["address"] %>">
        <param name="CONTROLS" value="imagewindow">
        <param name="CONSOLE" value="Clip1">
        <param name="LOOP" value="0">
        <param name="NUMLOOP" value="0">
        <param name="CENTER" value="0">
        <param name="MAINTAINASPECT" value="0">
        <param name="BACKGROUNDCOLOR" value="#000000">
      </object>
      <object classid="clsid:CFCDAA03-8BE4-11CF-B84B-0020AFBBCCFA" height="28" id="video2" width="500">
        <param name="_ExtentX" value="9843">
        <param name="_ExtentY" value="741">
        <param name="AUTOSTART" value="-1">
        <param name="SHUFFLE" value="0">
        <param name="PREFETCH" value="0">
        <param name="NOLABELS" value="0">
        <param name="SRC" value="<%=Session["address"] %>">
        <param name="CONTROLS" value="controlpanel">
        <param name="CONSOLE" value="Clip1">
        <param name="LOOP" value="0">
        <param name="NUMLOOP" value="0">
        <param name="CENTER" value="0">
        <param name="MAINTAINASPECT" value="0">
        <param name="BACKGROUNDCOLOR" value="#000000">
      </object>

1.aspx.cs:
protected void Page_Load(object sender, EventArgs e)
    {
        //string addr = Request.QueryString["address"];
        
        string path = @"D:\film\中华英雄\2.rmvb";
        Session["address"] = path;                     
    }
如果采用string path = @"D:\film\中华英雄\2.rmvb";视频能够连接正常播放；但如果采用另外一个页面传过来的值string addr = Request.QueryString["address"];如下
protected void Page_Load(object sender, EventArgs e)
    {
        string addr = Request.QueryString["address"];
        
        //string path = @"D:\film\中华英雄\2.rmvb";
        Session["address"] = addr;                     
    }
那么视频播放界面是出来了，就是不能播放，没有反应。请问，这到底是怎么回事呢？谢谢了先！
