Open the rar file, and you'll see the movie file and possibly a .txt or .nfo about the movie. And yes, VCDs (and SVCDs) can be burned onto a CD.
Although if you're thinking that you want to watch it on your DVD player, you might not be able to. DVD players only support certain encodings. Just a heads-up.
Oh, btw, for anything having to do with movie-copying, DVD-ripping, etc. go to
