I've never encoded a vcd  :)  but I believe mencoder's `-of mpeg` is a
newer option that may not make mpeg1 video that actually works.  In the
TOOLS subdirectory of the source is a script called `mencvcd` which
uses mplayer and mjpegtools to make vcds.  If you're looking for a gui,
maybe try avidemux.
