Increase the bitrate then. But keep in mind that it could still be possible
that the mpeg wont fill the CD. With variable video bit rate, the encoder
uses only the bit rate necessary. Even if you specify 5000, the encoder will
not use that value in practice because the VCD resolution can be encoded
with a much lower bit rate.
