the flv file is deffinately there.
i'll try changing the code. what is the MIME map for .flv extension in IIS?
Maybe the file is there, but IIS will not send it to the HTTP client if a correct MIME map has not been created. To create the MIME map, please follow these steps (takes Windows 2000 server as an example).
Create MIME Map for .flv files:
1. Select the site to configure in IIS, right click and select "Properties".
2. Under HTTP Headers Tab, click the "File Types" button and select "New Type ".
3. Enter ".flv" as the extension and "video/x-flv" as the MIME type and click OK.
