Change dvd country code to code free???

Ain't gonna happen.

ooooh, what a "rocket science" answer that is, Mr. UCLA...

Ain't gonna happen.

To get a region free DVD player you have to do 2 things:

1) patch out the region encoding in the DVD drive firmware. There's a group of people on the Internet that do this with regularity, and the vast majority of DVD drives have region free patched firmware available.

2) Patch out the region encoding in the DVD -PLAYER- software. This is easy to do in a computer, or you simply use DVD player software that ignores the DVD region codes the DVD reports. (lots of that around)

However, #2 is where your DVD players like the Pacifica get hung up. There are SOME commercial DVD players out on the market that have patched firmware. There are others that have hidden menus that people have discovered. Unless someone has taken the trouble to crack the Pacifica DVD player firmware, and release a patch, you are SOL unless you have a rom debugger and you know assembly language for the processor that is used in the Pacifica.

The smart thing is to NOT buy a car with an embedded DVD player, and instead buy an off-the-shelf DVD player that you know has a firmware crack for it available, and use that with a back seat hanger. As an added bonus, these are usually cheap enough that you can afford to get 2 of them for the cost of the in-vehicle DVD player, so each kid can watch their own movie and they aren't fighting over a movie choice, and if one of them gets busted, it doesen't cost you a thousand bucks to have the dealer fix it.
