I have been recently using a great new wordpress plugin on Artifacting to display flash movies. Examples of it in use can be seen here and here. The plugin is called FLV Embed and was created by Yaosan Yeo. I’ve tried several other plugins that perform a similar functions and this is by far the best one I’ve found so far. Ultra simple installation, tons of options and customizations, and ease of use make this a plugin worth looking into if you want to display .flv movies on your site.
