Мультизонность DVD Philips 634

 personally tried the hack for DVD 634 & was able to make it region free in first go !!!!
Procedure Confirmation :
1. Switch on the DVD and open the tray.
2. From remote . Press four times zero : 0000 + (the digit for corresponding region , e.g 1 for region 1 , 2 for region 2 and similarly ----- 0 for region free
(This means if u want region free settings then u need to press 00000 or for region 1 : 00001)
3. Message will be displayed on screen saying region 0 which means the DVD is region free !!
4. Thats it !! (U can check the region by open the tray and pressing the display button on the remote)
Note : Havent checked the limitation of numeber of changes , which is 25 times !! But it u change it region free then it works OK , so don't try to paly with process.
