How to capture .flv files from a pop-up flash player

Hi all!
I've spent my last nights trying to download .flv files from this web page:
http://www.salute21.it/ita/v_volontariato_sanita.php
The problem is that with Replay AV or WM Recorder 11.0 I can only download the .swf files. (which are the player interface)
In fact the URL is like http://www.salute21.it/ita/FVS_Salut...1_maccagno180K
Even URL Snooper doesn't help!
I think I get this problem because the video plays in a pop-up flash player...I've read in this forum that "Currently there are no stream recorders that can download RTMP protocol streams (from embedded macromedia flash player). "...and may be this is why i can't save the .flv file.
The only way to save those videos is to use screen video capture software??
Thanx in advance for help and sorry for my english!!
