Comment (by gogasca):

 Thanks for the help,
 I downloaded latest git:
 1001  wget http://codemonkey.org.uk/projects/git-snapshots/git/git-
 latest.tar.gz
  1002  tar xvf git-latest.tar.gz
  1003  cd git-latest.tar.gz
  1009  autoconf
  1010  ./configure --with-curl=/usr/local
  1011  make
  1012  make install

 Recompile videosnarf and ffmpeg and same results. I attached packet
 captures for you to try maybe you can find the right combination.
 Thanks!
