Most files in Pidip are GPL according to comments in the source code.
The "LICENSE.txt" does not apply to these anyway. Quote:

  This software is copyrighted by Yves Degoyon and others.  The
  following terms (the "Standard Improved BSD License") apply to all
  files associated with the software unless explicitly disclaimed in
  individual files:

It might also be important to note, that the "NOT FOR MILITARY OR
REPRESSIVE USE !!!" restriction is written *before* above statement,
which then say, that the "following terms" apply to the sources. So
the former restriction might not apply at all.  Rejoice, soliders and
dictators!

Here are some quick greps for GPL info in the source:

(externals/pidip/modules) $ grep -L "GNU General Public License" *
CVS
Makefile
Makefile.in
pdp_aging.c~
pdp_colorgrid.c
pdp_colorgrid.tk
pdp_colorgrid.tk2c
pdp_mp4audiosource.cpp
pdp_mp4audiosync.cpp
pdp_mp4config.cpp
pdp_mp4playermedia.cpp
pdp_mp4playersession.cpp
pdp_mp4videosource.cpp
pdp_mp4videosync.cpp
tk2c.bash

(modules)-$ grep -l "GNU General Public License" * | wc -l
75
(modules)-$ grep -L "GNU General Public License" * | wc -l
15

Distributing a version with the 15 critical modules removed would be
permitted.

BTW: PDP, on which Pidip relies, is GPL as well. While it may be
possible to remove EffecTV from Pidip, it is not possible to remove
the dependency on PDP. 

Ciao
