Had popup window working using AllVideos plug 2.4 by following directions here:
forum.joomlaworks.net/index.php?topic=97.msg1356#msg1356

I notices that there was no [jw_allvideos_player.swf] in version 2.5.3, looks like player was replaced by [mediaplayer_3.16.swf]

Replaced the code inserted into javascript popup ---

In trying to figure it out, uploaded the old [jw_allvideos_player.swf] to the players folder, and it works.

Is this file still supposed to be there, or is there some difference in using the code for [mediaplayer_3.16.swf].  I assumed that mediaplayer_3.16.swf replaced jw_allvideos_player.swf
