There is an error on the flv pages (at the bottom in the source code):
Fatal error: Call to a member function isDynamic() on a non-object in /home1/ericdmun/public_html/ericandcarmelita/pics/zp-core/class-image.php on line 688
Seems something is not installed correctly.
I have no idea then. Are you sure that the codec the flv use are supported by the flv player? Note that the plugin uses still flvplayer 3 and not the new 4 version (because that changed some options for styling). But except that a few options for color etc will not be available the flv player 4 should work, too. You can just try to replace the player file, Maybe that's it.
