Movieconvert can be downloaded at sourceforge.net directly via cvs. Under Linux you should use the following comand:
    cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/movieconvert co movieconvert
generate the configure script with:
    cd movieconvert
    ./autogen.sh
    (if you want special CFLAGS Options you can also do a CFLAGS="-Wall -g" ./autogen.sh)
generate the programm with
    make && make install
    (for make install you need probably an root account, you can also run the program from src/ Directory directly without calling "make install" but then you will get warning messages that movieconvert didn't find some pixmaps)
There are no *.tar.gz releases available at this moment. As soon as movieconvert enters alpha state, I will also provide such files.
