I'm not understand your problem completely, should it be redirect
or proxying ? Probably you need somethign like this:

  geo  $czech  {
       default         0;
       192.168.1.1/24  1;
       ...
  }

  location ~ \.(flv|mp4)$ {
      error_page   404  = @ext
  }

  location @ext {
      if ($czech) {
          rewrite  ^   http://second-server.cz$request_uri;
      }
      # what's here ?
  }
