It must work like that, I never said that I wasn't going to use an MPEG
decoder. Obviously, if the raw data coming out of the DVD drive can be
processed by the decoder to be displayed, it is obviously possible to
copy that same data stream and feed it into a decoder as well. Just a
matter of someone writing the software.

As I said above, Yeh sure! Movies studios, like almost all other big
business, want it all. When they realize that they are not going to get
it, they don't turn away profits by not doing it at all. Maybe that is
why videos average about $10-$50 now when they were $80 15 years ago.
The solution to piracy (at least mass) is to make it affordable enough
that it is more trouble than it is worth to pirate it.
Thanks!
