There really isn't an officially supported "region free" player because the manufacturers are restricted by DVD and bluray licensing to only be able to play discs in a certain region. You can buy hacks and modifications if you want. There's a region free plug-in kit on ebay for the Oppo 95 that allows you to switch the region for the player at any time. It's a manual process and will set the player to play from a specific region.
