DevalVR support

http://www.devalvr.com/paginas/soporte/ ... video.html
i did a new install of winxp. this way noscript is not installed in firefox.
adobe flash player 10 plugin is installed. but: i cannot run the integrated flashvideo. button is visible. also not working with shockwave-player installed.
big difference to my other winxp-drive where devalvr is working: windows security essentials installed.....

flashvideo inside panorama also not working anymore on my second hdd. ie7 installed. working before some weeks ago, maybe ie6.
i am totally confused with devalvr with video inside. how about a description what sort of video is possible and how to use. i know there is a tutorial. but if it is not working.
