sony dvp sr320 dvd player lockek how to unlock?

Hello,
This DVD player unfortunately does not support most of the Copied DVD /CDs.
it works stemless with only genuine / original CD and DVDs..
If your DVD or CD originally recorded by manufacturers but still can not read ,
than I recommend you to obtain and apply it to clean your laser eye of the DVD player.

The second problem is related with factory locked multizone feature..
on the rear of the player will be a region code plate with a picture of a globe and a
number next to it.If you DVD disc does not have the same ZONE number ,it wont work.
But in order to convert your DVD to a multizone you need to make some additional adjustment.
Hope it will solve your problem.otherwise ask me to give you more on unlocking multizone feature.
Please remember to vote me too..
Regards

Compatible disc formats: DVD, CD, CDR, CDRW, Video CD

Howdy,

I just tried this on LGV774W and it worked :))

To make this player region free (or change the region), do the following:

* Ensure that there is no disc in the player (ie: "no disc" is displayed).
* Press PAUSE
* Enter 314159
* Enter the region code (0 for region free, or 1-6).
* Press PAUSE
* Turn the player off for a few seconds.
* Turn the player back on
* Voila! You beauty!!

Alright, just follow these steps and let me know if you have any problems or questions

1. Power and switch on the Durabrand DVD player.
2. Open the DVD disc tray tray or lid.
3. Press Stop.
4. Press 3 - 5 - 9 - 7 (3597 in sequence). Can be done on remote control.
5. Hidden DVD Region menu appears. Select region 0 or 9 using up or down button on remote control
6. Press OK.
7. Close the disc tray and press Standby on the DVD player front

try this:
Multi-Region: 
• Turn On the unit with the remote controller 
• Wait until "no disc" appears in the unit's display 
• Press Pause, 3, 1, 4, 1, 5, 9 
• The word "CODE" should appear in the display 
• Within five seconds, press the key that corresponds to the zone you want i.e. 0 for region free, 1 for region 1, 2 for region 2 and so on 
• Again, within 5 seconds, press Pause and Power
hope it helps!
