How do you add flv files to your blog?

I just discovered how to convert WMV movie files into FLV movie files.

I’m sick of using youtube to upload my movie files and I can’t for some reason embed youtube footage within my blog posts – Internet explorer seems to report an error and closes down whereas Firefox does allow me to view embedded youtube files within my blog pages – why is that?

I enjoy using internet explorer when browsing the web and don’t wish to deviate away from it. So I looked into converting my own movie files into FLV. I tried uploading my flv file and pasting the file into my blog post. For some reason text only (the name of my flv file) and no link!!! I want to embed my flv movie within my blog post but don’t know how to go about it.

Do I need to download an flv plug-in?
