There are 2 types of output anolog and digital
There 2 types of digital output - Coaxial and Optical
The anlog output requires the DVD Player to have inbuilt decoder to seperate the volume of each channel so as you said that you have seen
some players which have output for front speakers , rear , center , etc.
that is a anolog output.
Its not so that only Indian DVD Players have Anolog Output.
Its better to have one as not all go and purchase a 5.1 Speakers Set.
And its always good to have a Set of 5.1 Speakers that 2 Channel
[Stereo] Speakers just playa movie on 5.1 with all those beautilful
effects of sound they make you feel as if you were in that place ,
such a feeling cant be acheived with Stereo Speakers.
Well hope so that you have got ur answer
