你可以改Regional Code的
一般Coby的过程 （ZT)
with no disk in the player press:
Setup, Vol+, Vol-, Vol+, Vol-

in the right upper corner a current region code would appear. You could switch between 1,2,3,4,5,6 or 255 using Right and Left buttons. I beleive, 255 is for multy-region.
If you press Up (or Down) button you can get into macrovision menu from here. Again, using Left or Right buttons switch between 3000 (Off) and 3001 (On) values.

DVD-player keeps these new settings even after powering Off.
