I put the swf, skin.swf, and the flv and html file on the same root directory.
I also did
Associated Extension box: .FLV
MIME Type box:flv-application/octet-stream
on my server. It works offline. However, It just does not work on the website. Please see attachment.
what tool do you use? how do you generate the swf and flv? "Embed video in SWF" or "Progressive download from a web sever", and check your browse have installed the latest adobe flash player. You don't need to change the generated html code, if you need, take a look at this tutorial in detail , http://www.flash-video-soft.com/blog/?p=196
Hope it helps,
have you set the security domain to network rather than local? also, you might like to consider adding some trace statements in a text box to ensure that the FLVplayer is able to connect, is not experiencing errors etc.
