	Is there a corresponding dvd player expected?  It seems odd
to have

Did anyone notice that the code itself hasn't been touched
since 2004? 
The dev list looked pretty dead too. If its good stuff to
have it 
doesn't need to be updated all the time but I think it begs
the question 
if we're adding in morbid code....though maybe not an ARC
concern.

Yes. The Ogle player is planned for implementation as part
of Indiana by 
Dermot McCluskey.  He doesn't currently have a target
integration, but 
supports our integration of this now.

The Ogle player is licensed under the GPL.  This means that
you cannot
link any any non-free code.  Since DVD's (even unencrypted
ones) are
encoded in MPEG2 formats, you cannot distribute Ogle with
MPEG2 support
even if you have a license to distribute MPEG2.  The Ogle
player would
require a GPL exception to allow distributing it with
support for MPEG2
codecs.

Is your plan to only support unencrypted DVD's that are
encoded in free
video/audio media formats, such as theora?  I don't think
any such DVD's
exist, unless you make them yourself.  It seems we should be
integrating
a DVD player that can be distributed without violating GPL.

Further, I notice in your OSR (8050) that you didn't
highlight any
patent issues in the Engineering section, question #9. 
Isn't it fairly
well known that DVD technologies are heavily encumbered.  I
would
think we should be highlighting that a careful look at
patents is
required in a case like this.  No?

There are at least two completely separate issues here that
I think
you're blurring together.  If it were true that GPL Ogle
couldn't use
a "non-free" library, then it couldn't use the
non-GPL libc on S10,
nor could any other GPL code.  I've never seen GPL
interpreted that
way, and it doesn't sound quite right.

The _separate_ issue is the patent one.  GPL requires you to
include
grants for any patents required to use the software, or GPL
just
immolates itself in a fit of pique.  If there are such
restrictions
that apply to the navigation menus (really?), then that's a
real
problem for this project.  (And probably the upstream author
as well.)

In any event, neither issue is really architectural.  These
are things
for the project teams to discuss with their lawyers, and
make sure
they're doing the Right Things.

An architectural issue would be:

	So what's the deal with libdvdnav and libdvdnav2, and
which
	variant are you really shipping?

That's a matter between the project team and their lawyers. 
It
certainly should _NOT_ be discussed on an open list like
this.  Please
stop here.
