Hi Zahid Ali,
Thank you for getting back to me.
The editor's managers work with files that can be rendered and displayed by the browser, e.g. images, links, swf and movies. That's why, the Flash manager does not allows .flv / .fla files, because they are source code files and they cannot be rendered by the browser.
That is why, currently, we do not plan to provide direct support for FLV files, because in order to play FLV files you need to use a specific FLV player, which is not free.
If you wish to play FLV files should first get a key for a certain flash player, and then a user control which will wrap the player you are using. Similar cotnrol (working with swf) can be found in this forum thread: Add SWF o0r Flash video in the pages.. If you have a flash player you can modify the control to fit your needs.
