I've converted a wmv into an flv so that I can upload it to my site but when I try to upload and install the file into ...cloudaccess.net/httpdocs/images/stories - I get an error message: file type is not supported. What do I need to do so I can upload an flv to my site?
Thanks in advance.

Go to site/global configuration

in the media settings/ Legal Extensions (File Types) add flv :)
