This might be off topic, but I hope someone here can englighten me.

I know Dolby Digital 5.1 and DTS are too different audio format in DVD.

Almost all the original DVD that you can find in Speedy (either local released or imported ) or www.buy.com, all the new released titles only have DD 5.1 .
There are only few that special edition titles that have DTS.

And almost all the pirated DVD in malaysia that has both DD 5.1 and DTS.

My question is, who encodes the DTS into these pirated DVDs?
The original studio or the pirated industry?
if the formal one, why I can't find any original title that has DTS version?
if the latter, how they get the audio track that the original version not even exist? And is the DTS in these DVDs really a true DTS?

I know DD5.1 and DTS are not much different.
But it bugging me that my original DVDs only have DD5.1 and those pirated DVDs out there have both.

I don't think it is region thing wo.

I buy most of my DVDs from buy.com or amazon.com which is region 1. But all the title only come with DD 5.1

Using Pirates Of The Caribbean - Dead Man's Chest for example.

It released 5 Dec in US.
This is Region 1 from amazon.com
Pirates of The Caribbean: Dead Man's Chest - Region 1

This is Region 3 from Playasia.com which released 28 Nov in Hong Kong.
Pirates of The Caribbean: Dead Man's Chest - Region 3

Both only come with DD 5.1

Where does the DTS version come from then?
