Direct embed method is listed as unavailable. This might actually be a bug? Status page shows:

"Default method swftools_nojavascript
This method no longer appears to be available. Check the modules page to ensure that the necessary module is enabled, or choose a different embedding method on the embedding settings page."

Embedding with javascript seems to work fine when enabled. Maybe I just missed something but this looks like a bug? Tested in Firefox 3.6.6, Chrome 5.0, Opera 10.6
