Hi, it is pretty common for some brands and types of DVD players to have a region setting that is:
- changable by remote. That is, you can set the region for each disk you play (to either 1, 2, 4 or something else) Sometimes this is limited to a specific number of changes though.
- changable to R0. That makes the player all-region but does not work with some DVD, especially the ones that are RCE.
Google for <type> + region free or region hack.
Also, if you have to send your player to Europe for modding, it may be cheaper to sell you existing player and get a multi-region, multi standard (PAL/NTSC) and multi-voltage (110-240) unit from the UK.
