2 questions about these players.
Firstly what is the difference between the 2 models??
Secondly are either able to be region hacked or do I need to buy a 'chipped' machine??

I think that the only difference may be colour (silver/black) although not 100% sure. Can anyone confirm?

As for hacking it - up to this point Pioneer players can only be chipped, not handset hacked, so I doubt this player will be any different.

One only has an optical out (the silver 530?) and one also has coaxial out (black 535?). They always seem to be the same price so maybe this is them trying to encourage you to buy the black one?
