| All Region (Region Free) DVD does not mean it plays everywhere in the world. | |
|
There are two levels of restrictions on a DVD. First, the DVD format must match TV system that the DVD is played.
Second, among PAL or NTSC countries, there isa next level restriction
called Region code.
|
|
| What does Region Free or All Region DVD video? | |
| "Region Free" aka "All Regions"
DVD means that the DVD will play any counties as far as TV
system is the same. PAL Region Free DVD = it will play any PAL countries. NTSC Region Free DVD = it will play any NTSC countries. These is no such a DVD that will play all over the world, because
DVD video must be in either PAL or NTSC. Examples on PAL / NTSC problems

Players.

|
||
| DVD video has two issues, one is TV system (=PAL/NTSC) and other is Hollywood (=Region code) | ||
|
There is no such DVD that will play on TV in all over the world,
not because of regional restriction but because of the difference
of TV systems.
|
||
| Viewing on computers has nothing to do
with PAL/NTSC TV system issues, but Region code issue might or might
not occur, depends on the DVD device and/or driver setting.(note *1). You can watch NTSC DVD in a country of PAL TV system, or you can enjoy PAL DVD on your PC/Mac in the US.
