        Minor correction (if you don't mind too much ;)).   It's mplex
        that does the padding as I recall.   You'll have a .m1v file
        of the expected size and then when you mplex it you end up with
        this huge file that's padded out to the maximum (CBR) rate you
        give.

        For creating VBR MPEG-1, yes, you need the -V option to mplex

        Cheers,
        Steven Schultz
