29/05/2014  23.28            58.675 libgstvorbis.dll

the file is different.
libgstautodetect.dll, libgstdirectsoundsink.dll,libgstdirectsoundsrc.dll
are absent.
Now I think that the problem is this.
The copy from an installation to other installatin do not work,
remote-viewer do not start.
I think that it need to rebuild gstreamer library of the mingw.
I'll try.
Gianpietro.
