Por el multizoneo no hay problema, porque ya tengo en casa el chip de Bluraychip.dk , espero no cargármelo cuando lo instale! jeje
En el último sitio localizado donde se ha hecho referencia al problema es en esta review inglesa en la que comentan el modelo europeo (en teoría exactamente igual que el americano):

Esto es lo que dicen con respecto a la reproducción PAL:
"The Oppo DV-983H was critically acclaimed for being able to flawlessly handle just about any NTSC disc that you threw at it, but for a European audience, there were still a few issues with its 2-2 cadence detection (this is the case with several players, irrespective of pricing). Although the issue could be worked around easily by simply forcing the correct mode in the player's menu, it meant that there was no "set and forget" mode for getting the best from PAL Film DVDs. So, I started out by seeing if things have improved with the BDP-831.
Sadly, things are much the same. In the "Auto" and "Film Bias" deinterlacing modes, cadence detection for PAL Film material is attempted, but it was not entirely successful with our test material (the PAL HQV test disc as well as several PAL movie titles). The player would stay locked on to the Film content for part of the sequence, but other times, the machine would incorrectly identify the contents as Video, creating subtle flickering. Most users aren't going to notice, but the problem is there. Fortunately though, as with the DV-983H, you can still manually force the player into deinterlacing PAL movies correctly by entering the "HDMI Options" menu and selecting the "2:2 Odd" cadence option (or much more rarely, "2:2 Even"). The fact that there's no true "set and forget" option is a little disappointing, but not entirely unexpected: many players struggle with 50hz 2-2 content and need to be manually instructed. Hopefully, Oppo can improve this ease-of-use with later firmware updates, but the fact that it's a slight annoyance carried over from their high-end DVD player makes me speculate as to whether it's a limitation of the Anchor Bay VRS chip itself.
PAL DVD backwards compatibility is about as good as most other players in this price range: the Oppo BDP-831 needs to be manually instructed to deinterlace 2-2 material to get the best possible quality from your PAL DVD collection, and doesn't have a flawless "Automatic" mode for this task - at least, not at the time of writing. Because Oppo continually improve their products, I look forward to seeing if they can overcome this annoyance."
Aparentemente el problema se soluciona configurándolo a mano en su menú. Lo que no se es si habrá que hacer eso cada vez que vaya a ver un dvd PAL, es decir que dependiendo de si veo uno en NTSC o PAL voy a tener que entrar en el menú para cambiar ese parámetro.
