Strange problem with flash videos

Rails
1

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:

And that thing is the script for the video:

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 !
