[Plugin: Shadowbox JS] Continually play an XML Playlist (Shadowbox-JS / JWPlayer)

Anyone know how to continuously play an xml playlist using JWPlayer that comes with Shadowbox?

I know that the flash var needed for JWPlayer to continuously play through an xml playlist is “repeat:list” (without this, the player stops after playing the first file in the playlist, where I want it to continue on to the next file).

I think I need to add this var somehow to the Shadowbox-JS plugin code, so I looked at shadowbox-js/shadowbox/players/flv.js and cannot figure out for the life of me how to add this here.

Does anyone have any suggestions? Thanks!
