Strange output message when testing

Full output message:
1000: Unable to make connection to server or to find FLV on server

I have a movie with 8 buttons. 4 call a simple movieclip that displays a text quote. The other 4 display a FLV. If i test the movie and click one of the Text related buttons first, the above message appears in the output panel. And other scripts do not run correctly.

If I click one of the FLV buttons first, the movie plays fine and no errors or script issues occur.

Has anyone run into this issue before?

Thanks in advance for any help.
