I was having some trouble getting a FLV files to play on a web hosted on Windows 2003 Server running IIS 6.0. This was because there was a missing MIME Type in IIS. You can also use this method to add other plugins like SilverLight.
- Select the site to configure in IIS, right click and select “Properties”
- Under HTTP Headers Tab, select “File Types” under the MIME Map section and select “New Type”
- Type “.flv” as the associated extension and “video/x-flv” as the content type.
- Select “OK” and you’re ready to flv!
Takes a few minutes to show up on the site…I restarted IIS
