i've a very strange problem with a NetStream Buffer only in Internet Explorer (flash player version 10,0,32,18).

When I connect to a netstream I use this:

var videoOpe:Video=new Video();
var stream="name live stream";
var nsOpe = new NetStream(nc);     //nc is an active netConnection
nsOpe.bufferTime=1;
nsOpe.client=this;
nsOpe.play(stream, -1,-1)
videoOpe.attachNetStream(nsOpe);
                                 nsOpe.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);                   nsOpe.addEventListener(AsyncErrorEvent.ASYNC_ERROR, asyncErrorHandler);

Well, in mozilla, safari, opera and when I compile in flash, evrything works fine. But in IE I see like a double buffer, this is what I see if I do a trace of NET_STATUS:

NetStream.Play.Reset
bufferLength: 0.001
NetStream.Play.Start
bufferLength: 0.001
NetStream.Buffer.Full
bufferLength: 1.021
NetStream.Buffer.Empty
bufferLength: 0
NetStream.Buffer.Full
bufferLength: 0.857

It doesn't matter the bufferTime I put.
Any idea??

Thanks
