No es muy legal hacerlos "region-free" ,con lo que no creo que lo ponga el la web oficial...
Pero de muchos modelos se conoce el menú ocultyo para cambiarlo, ya que el fabricante suele incluir el cambio de región en el firmware, por si tienen que cambiarse por motivos comerciales

Busca en Internet "Region pHILIPS 630 DVP

Yo encontré ésto en www.videohelp.com


The DVP630 I bought was region free on delivery (Audio Video, Sweden), but I hacked the remote control sequence required. The hack has been confirmed to work on the US version DVP642 as well (http://www.videohelp.com/dvdhacks.ph...ilips+DVP+642).


The hack should be perfectly safe, but USE IT ON YOUR OWN RISK!


From http://buan.nu/philips/dvp630/regioncodehack.html:

1. Turn on the player.
2. Open the tray.
3. Press the following sequence on the remote: 7 8 9 OK 0
4. The number 0 will appear on the lower left side of your screen.
5. Your player is now region free! Put in a DVD and enjoy!

NOTE: The 0 in the sequence above represents the region code. 0 = region free. If you want to change your player to just a specific region code, replace the 0 with the region number you want.

Pruebalo por si acaso...

Saludos!
