setting DVD region code

[pteeter]

I found this old thread…

https://www.afp548.com/forum/viewtopic.php?forum=29&showtopic=9668&highlight=region%20code

Anyone have any further ideas on how best to preset the DVD Region Code for use with InstaDMG?

I haven’t even investigated it yet. I will, I will.

Just wondering if anyone has already looked into it.

OK, I believe you. Though research turns up some fun firmware hacks to make an optical drive region free. 😈

So the section of /etc/authorization would be (in Leopard):

 <key>system.device.dvd.setregion.initial</key>
                <dict>
                        <key>class</key>
                        <string>user</string>
                        <key>comment</key>
                        <string>Used by the DVD player to set the region code the first time.  Note that changing the region code after it has been set requires a different right (system.device.dvd.setregion.change).</string>
                        <key>group</key>
                        <string>admin</string>
                        <key>shared</key>
                        <true/>
                </dict>

So to work around this for non-admin users, change the class to ‘allow’ and lose the ‘group’ and ‘shared’ keys?

Anyone got suggestions for editing this – payload free + postflight script? Or maybe best practice is to copy in a pre-built file?

pteeter,

I think I’m doing this with a payload free package, but it’s at work and I’m not. This turned up from a Google search, so YMMV:

http://jeffstrauss.com/?p=54

#!/bin/sh
"$3"/usr/libexec/PlistBuddy -c "Set :rights:system.device.dvd.setregion.initial:class allow" "$3"/etc/authorization

Tomorow I’ll double-check what I’m actually doing.

You plistbuddy stalwarts.

/usr/libexec/PlistBuddy it is.

Good call.

[Patrick Fergus]

Yep–that’s what we’re doing with our build.

FWIW I’m more comfortable with defaults, but defaults won’t touch anything beyond the simplest plists.

Somewhat off-topic, but does anyone know where to find a list of the valid keys?

I’d love to get some granular control and pick and choose what non-admins can do.

This article has some information:

However, we’d love a lot more granularity as well.
