diff one?
The GDV620 is one of the easiest hacks around.
1.Power on,and open drawer.
2.Key in 3838 with handset.
3.A menu will appear,"Region Code",and "Macro On/Off".
4.Region code can be set by pressing Enter key repeatedly to get desired region,and Macro,on the line below,can be accessed with the "down" button to be turned off if you wish to tape any DVD's.
5.Press Open/Close button to store.
As yet, I dont know if there is any limit to the number of times it can be changed!!
