Is the Oppo you made region free is BDP 93 or 103. If it is 103, please let me know detais of hardware modification.
Sorry for not being clear - mine is the older 93 model. From what I can see the 103/105 comes multi-region for DVD only, but mod kits are available for making the BluRay also play all regions.
