I have a Philips 723 Region 2 player. I would like to make it multi-regional. Has anyone tried doing this using the Philips 750 hack and if so, was it successful? Does the hack make it multi-regional, or does it simply convert the player to region 1 use? Also, has anyone experienced problems with the machine locking up after a certain number of region changes. I intend to use the players own remote. If the hack does not work, does anyone know of one that does? Many thanks in advance.
