Strange problem with flash videos

Hi everyone i am making a RoR application that contains flv videos like youtube. It has worked ok when i embedded the flv videos in moodle but now i have a very strange problem First of all I use the FLASH PLAYER 3.3 which is a quite common player. I have uploaded the videos in the public folder and i have stored their path in the db When i enter (so far you can access the app (from the Internet)) http://etsl.imm.demokritos.gr/word it works and i can see the videos when it changes to http://etsl.imm.demokritos.gr/word/ i can see nothing and no Javascript complaints !!! Plus the output HTML is the same as before. So bizarre ! Also i made a contoller to view the videos by category, it works it produces the right HTML but the videos do not load neither the player !

Any ideas, suggestions ? I do not think anyone has encountered something so strange

Just to add something I just checked with WebRick as i said when i add a slash at end the videos do not appear and webrick gives me that:

Processing Base#index (for 91.140.18.241 at 2007-05-11 23:31:17) [GET]   Session ID: bc651fe3d0fac25477d5af2c51212ea4   Parameters: {}

And that thing is the script for the video:      <script type="text/javascript">       var FO = { movie:"flash/ flvplayer.swf",width:"320",height:"240",majorversion:"7",build:"0",bgcolor:"#FFFFFF",       flashvars:"file=/videos/animals/ animal_uk.flv&showdigits=false&autostart=false&showfsbutton=false&repeat=false" };       UFO.create( FO, "player1");           </script>

The strange think is that even when i give directly the link: http://143.233.16.42:3000/word/category/2 It still produces the same error !
