Recently picked up the "Limited Edition" disc which was released a couple of weeks ago, because I previously only owned this on VHS...does anyone know if there is a U.S. DTS version of this DVD available, and are all the DD 5.1 mixes on every version of Independence Day, including this Limited Edition, all carryovers? I have read that Japan has gotten a full-blown Ultimate Edition with DTS and awesome packaging. Are all ID-4 releases in the U.S. DD-encoded only?
