I am getting an undefined jscript error on a page which has an embedded floplayer script for playing back flash flv files.
The player has a img tag which is clickable to start the movie. Clicking on this link gets the undefined when trying to get the hostname.
In the uncompressed code it breaks on 667:
667: sourceHostName = originalSourceHostName.toLowerCase(),
originalSourceHostName is undefined
Adding a check for hostname got me around the symptoms but is probably not the best means if clicking this item is trackable.
