1. Flash CS3里面无法向FLex一样调用文件的问题
下面这种方式在CS3里面无效,

[Embed(source="zhaiduo.jpg")] private var zhaiduo:Class;

我们可以把文件导入库library, 通过linkage ID调用。如:linkage ID为"Zhaiduo"。

var zd:Zhaiduo=new Zhaiduo(100,100);
var myBitmap:Bitmap = new Bitmap(zd);

2. NetStream无法播放非本地FLV视频文件的问题
NetStream只允许本地bitmapData.draw。所以只有声音看不见影像。例子可以看里。
Nabble上有这样一段解释：

The only way around this is to deliver your video via a custom
configured flashCom server. (Open source solutions include red5 and
haXeVideo). These flashCom servers have to send a flag with the
NetStream that allows bitmapData.draw for your domain. Regardless,
you aren't going to get this from a remote server.
