在线文档播放有关问题：播放器加载flash失败

在线文档播放问题：播放器加载flash失败
在网上找了phpcms百度文库插件（源程序就是phpcms的），照着做了下，转换都成功了，就是在显示的时候转换好的flash老是加载不出来（播放器正常加载），求解。
转换所用工具：OpenOffice3.0、Windows Resource Kit Tools和swftools。
先上显示页面代码：

网上找了一圈，有人说是下边这行错了，

PHP code

<!--

-->
SwfFile : escape("{$r[filename]}"),

应该改为：

PHP code

<!--

http://www.CodeHighlighter.com/

-->
SwfFile : decodeURI("{$r[filename]}"),

但我改完后还是加载不了swf，
还有说是swf文件名含中文或者是swf文件被放在文件夹下了，于是我在根目录下放了一个转换好的swf文件，并把上段代码改为：

PHP code

<!--

SwfFile : decodeURI("a.swf"),

或
