For me the player does not show at all.
I have downloaded the 5.7.zip file and placed it's contents in the correct directory.
I have disabled the plugin and re-enabled to no avail.
Using apache2 on ubuntu server viewed with IE 8 Windows XP SP3.
When viewing html source I see the tags used by the player.
Only customization is the flv videos are on the same server in a directory outside WP.
Videos were working before we installed the latest stream video player upgrade.
Since the site also contains personal information I cannot post a public link to it.
Here is one of the tags:
