Hi,
Apologize me, as this may be not the perfect answer, but it works!!
I had the same problem and here goes the work around that was perfect.
1) Right click in your video and choose JW Player or just follow this link:
www.longtailvideo.com/players/jw-flv-player/
2) Download to your computer zip file without the viral tick activeted!!!
3) Unzip it locally
4) Go to your server ftp: and inside folder: "/httpdocs/plugins/content/jw_allvideos/players" rename 'mediaplayer_4.3.swf' to something like: 'mediaplayer_4.3.swf.old'
5) Upload your player.swf from locally and reame it to: 'mediaplayer_4.3.swf'
Et Voila!
Bye this boring link!
Hope you solve your problem like I did.
