[Mp4-tech] mpeg-j problems

[Mikael Bourges-Sevenier]

Dear All,
If you are an MPEG member, you can access MPEG source code repository and
hence the latest code and tools.
Personnally, I tried MPEG-J with JDK 1.4.x, IM1-2D and Player3D without any
problem; just follow carefully the procedure in docs/Player3D_setup.doc.
Kind regards,
Mike
