The following was posted on the Official Xena Convention page for next January's con. Not sure if this was the way it's been or Creation has changed the rules.
Note: Due to the high volume of entries for our Music Video Contests, we are forced to limit entries to those people actually attending the specific show they are entering for. You do not have to be present for the actual showing of your video, but you must claim your award on site before the end of the weekend or your award will be forfeited.
