[COLOR=#000000]In the docs from [Adobe.com](http://Adobe.com),  
it says: [/COLOR]  
[COLOR=#000000][/COLOR]  
[INDENT][COLOR=#000000]Cross-domain policy files affect access to a number of assets, including the following:

- Data in bitmaps, sounds, and **[COLOR=red]videos [/COLOR]**
- Loading XML and text files
- Access to socket and XML socket connections
- Importing SWF files from other security domains into the security domain of the loading SWF file

[/COLOR]  
[/INDENT][COLOR=#000000]But when I tried to access the videos on Youtube, I found it possible to load and play, seek completely. But checked this file, [http://www.youtube.com/crossdomain.xml](http://www.youtube.com/crossdomain.xml) it did not put my domain on it. (not only locally but also when putting my swf on a server) So why sometimes we can access the flv files but sometimes we cannot do that with XML files? It’s really weird [/COLOR]
