Dreamweaver cs4 unwanted displayed message

Hi,
can someone help. I am new to webdesign. Each time I insert a swf or flv to one of my pages, when I view in windows explorer, I see a message "contents on the page requires a newer version of adobe flash player plus the adobe logo to get flash player.
I have the newest players installed.
I want to completely take this away from the design code.
Can anyone tell me what parts of the code to delete or how I can stop this being from being added to my web pages.
On my index page I've type a description, If my videos don't play please download newer versions of the flash player. Thanks Kelvin
