Nucleus Plugin FlashVideo
 
With this plugin you can post a Flash Video (flv) by using the tag <%flashvideo(yourvideo.flv)%>
 
The plugin requires the FLASH VIDEO PLAYER (http://www.jeroenwijering.com/?item=Flash_Video_Player) from Jeroen Wijering. The player file 'flvplayer.swf' must be in the directory /media of your blog.

				   - parameters for individual width and height of the video added

v0.5 (2007-02-07): - additional parameters to style the player
				   - automatic search for preview images (required for the new
				   version of the fash video player)
				   (used version: FLASH VIDEO PLAYER 3.3) 
v0.6 (2008-02-14): new option to decide which filename is used for the player:
				   - 'mediaplayer' for newer versions
