not so fast....

"you can copy a entire dvd with windows explorer, but still need a LICENSED player to play it, no one cares about copying, it is losing control of the player they care about"

Ummm... not completely true. If you want full details do a search, but its not possible (with easily available affordable home equipment) to make a "clone" of a commercial DVD.

A commercial pressed DVD has some tracks that hold the region/encryption/etc data. The video & sound is encoded & encrypted in the .vob file.

A copy utility like 123 could copy a .vob but can't write the extra information onto a blank consumer DVD as they physically can't hold it. Pro-sumer "mastering" writers can but require the appropriate mastering media.

Therefore a product like 123 has to decode the videostream in the .vob and recode it to do the "duplication". Plus many pressed DVDs have more than 4.7GB so features or quality need to go to fit onto 4.7GB blanks and to do that the stream needs decoding.

It is the "circumvention" of the copy protection mechanism under US digital encryption legislation that is the issue. If a simple bitwise cloning went on (as it essentially does with CD duplication) then there's no case that can be made under this legislation... or else Roxio, Nero and all the others would be in hot water already.

I don't know what you are trying to get at by reference to a "LICENCED" player. These players will quite happily play ripped DVDs. Plus all the ones I've owned have not so "secret" menus that allow the region to be changed at will and indefinately.

I'd say they ARE bothered by the copy-ing and/or transcoding of their material.
