Description of problem:
looking at the spec file in cvs.
BuildRequires: gcc-c++, libdvdread-devel, libogg-devel,libvorbis-devel

libdvdread is not in extras... as a result ogmtools as currently
implemented in Extras isn't going to build cleanly.. if its ever
requested to be built. Either ogmtools needs to be pulled out or
libdvdread needs to be included

Now I've had a little discussion with some other people about whether
or not libdvdread can be included into Extras. The finer technical
points are just beyond my feeble brain's comprehension, but I'll give
you my limited understanding of the situation as was explained to me.  
libdvdread should be okay to include in Extras because libdvdread
dlopens libdvdcss. Its libdvdcss that can not be included into Extras.
The outstanding technical question becomes... what happens if
libdvdread goes to dlopen libdvdcss but can't find it? If libdvdread
and applications that use libdvdread can handle the situation when
libdvdcss isnt available then there shouldn't be any problem including
libdvdread into extras.

I'm not equiped with enough understanding to facilite a discussion on
the matter, so I'm bringing it to your attention in the hopes you can
find the best solution that works for the ogmtools package. As it
stands now ogmtools can not be built because libdvdread-devel is not
part of Extras or Core.
