It's indeed mpeg, and a system stream (so a muxed mpeg file, not an
elementary video stream). You need to demux them in some way. I don't
know how to do that with mplayer/ffmpeg. With GStreamer, it's
"gst-launch filesrc location=file.mpg ! mpegdemux .video_00 ! filesink
location=file.m1v". I'm sure Steven knows the proper ffmpeg command, and
others will know the right mplayer command.
