Hi all,

I recall some time back on the list talk of tools to report and strip the DVD 
region encoding on a DVD.

One user came up with one to report the region encoding being used by a 
particular DVD, located at http://busy-bee.net/files/show_region.txt

Last night I had the need to strip a DVD's region encoding and after scouring 
the mail archives and Google, came up with none.

So this morning I wrote a very simple one (my first C++ program):

/* File: dvd_region_free.cpp
   A tool to force a DVD to be region code free
   Author: Rick Harris  [EMAIL PROTECTED]

   Installation: Run `g++ dvd_region_free.cpp -o dvd_region_free` to compile,
                  then `cp dvd_region_free /usr/bin/dvd_region_free`
   Usage: /usr/bin/dvd_region_free /path/to/VIDEO_TS.IFO
*/

#include <iostream>
using namespace std;
#include <fstream>

int main(int argc, char** argv) {
    if( argc != 2 ) {
        fprintf( stderr, "Usage: %s VIDEO_TS.IFO\n", argv[0] );
        return -1;
    }

fstream File (argv[1], ios::in | ios::out | ios::binary);
   if(! File) {
        cerr << "File does not exist!\n";
        exit(EXIT_FAILURE);
    }
    File.seekp (35);            // Seek to region code byte ready to write
    char buffer[1] = "";
    File.write (buffer, 1);     // Zero the byte
    File.close();
}


Or if your mail client wraps weirdly, can be downloaded here 
http://mightylegends.org/dvd/dvd_region_free.cpp

Simply seeks to the 35th byte in VIDEO_TS.IFO and over-writes it with a zero 
byte.
Each of the 8-bits of the 35th byte represent one region, so if the user 
really wants to modify this they could also use it to create their own region 
encoded discs by flipping the relevant bits.

Hope someone finds it useful.


Cheers,
Rick
