What is Region Code Enhancement (RCE)?
RCE is a way devised by some of the major film studies to prevent DVDs playing on players that have been modified to play DVDs from regions other then the region of purchase. In reality RCE is little more then a mechanism designed to trick you player into admitting it’s not a genuine Region (X) player. Similar systems have been used by Disney in the past and all of these systems can be avoided if your player has an option to manually set the region. Most automatic modifications also work with RCE with the exceptions of some older chips for Toshibas.There is a dedicated FAQ on the subject at DVDTalk http://www.dvdtalk.com/rce.html this also includes a list of RCE titles.
