The following answer was found on videohelp.com
The DVD needs to be put in service mode.
1. Start DVD and wait for disk to load.
2. Press and hold the Stop and Eject keys simultaneously, then turn the
volume nob until the Service menu appears.
Now, follow the procedure below to convert the DAV-DZ11 player to multi-
region:
1. Hold the magic button until it flashes twice.
2. Press DVD
3. Press 0533 (flashes twice)
4. Hold the magic button until it flashes twice.
5. Press 994
6. Press Magic Key (don't hold)
7. Press 00189
8. Press 1 ( this sets it to key 1 - it flashes twice )
Now program function codes into buttons 2-5 like this:
* Repeat steps 4-6, then 00255 2
* Repeat steps 4-6, then 00095 3
* Repeat steps 4-6, then 00221 4
* Repeat steps 4-6, then 00079 5
To actually convert the DAV-DZ111 DVD to region-free:
13. Press 12345 - Recorder goes back to standby
14. Press 12345 - Recorder starts up
Notes:
1 - Unlike the instructions for other Sony DVDs found here and elsewhere,
the device should be powered up -- the hack procedure will not work with
the DVD in stand-by
2 - Player does not display "SUCCESS" or "TIMER OK", it simply powers down
then powers up
3 - I used an OFA Kameleon 4, but I am sure it can be done also with other
programmable remote control units. Some programmable remote controls
require a 3 number code; just drop the two leading zeros from the code (i.e.
00189 becomes 189).
