While working on my daughter's web page and trying to make some flv files running on the site, i noticed that it did not work, at least not with IIS6.

After some googling i found out that is needed the flv MIME Type to be defined for the particular site.

Here are the steps tat need to be done:
1. open Properties for your site
2. open the "HTTP Headers" tab
3. click "MIME Types..." button
4. click "New..."
5. for Extension set ".flv"
6. for MIME type set "video/x-flv"
7. click "OK", again "OK" and... again "OK"
