First, I will not repeat what Romain said, i perfectly agree with that,
i wouldn't have writtent better.

Let's see, that line #159 :

"However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable."

QuickTime IS a major component of MacOS X. You cannot install MacOS X 
without
it. There are no possibilities to have a MacOS X system without 
QuickTime.
My codec is written for MacOS X, so it implicitly requires MacOS X which
is not GPL the same way as Emacs for Windows implicitly requires ...er 
Windows!

That's not the point. No one talk about integrating parts of MPlayer. 
The
codec remains well separated and could be used with others compatible
libraries, such as openquicktime.

Well, yourself were not proving a special knwoledge of QuickTime and its
mechanisms some emails before... Whatever you call it, the matter is 
that
the system in a way or in another is calling executable code stored in
a file. That could be a GPL part of the system, a proprietary part such 
as
the Finder (~ Explorer under MacOS X) or the QuickTime Library.

You bet?

The guy was not talking about GPL's politics which is very good.
Maybe i will ask the FSF about that matter, but to me the problem is 
that YOU don't
want me to use MPlayer's parts in my GPL software. I don't understand 
why you
continue to argue about GPL. Just say "no", that's you right, and I 
respect it.
You don't have to insult me or me dishonest.

I agree.
