flashvideo module no player load

I have messages from flashvideo it tells me that create thumbail and video succesfull, i see on the dirs of my server and flashvideo created perfect on the directory output i created, but after create page i can´t see nothing on the new node, i tried copying jw player inside output directory and i copied too to files default dir and nothing simply no video only a blank node. I renamed to Player.swf
this test i made with both player dashPlayer y jw player and i copied on both dirs video_outpu and files and nothing. Only the system creates a node with nothing, but the strange is the video compressed and the thumb picture are created perfect and are inside the correct dir the problem is only to display the player. I checked the compressed files to see if not corrupt and are perfect there is no trouble in compression or thumb image.
Any suggestion?
I think is a minor detail but in the case i need to pay something to help me configure we can talk.
Is some urgent
Thank you
