Not enough information to answer the question. What frame size are
you encoding for? DVD, VCD, SVCD, CVD, custom size ?
If 1000 is all the encoder needed then you have very clean source
and are probably encoding a 352x288 or so size.
I don't see where you specified the output format with a "-f" option.
"-f 8" is for DVD, "-f 1" for VCD and so on - see the usage() summary
for mpeg2enc (or the manpage).

Try giving "-f" and setting the format and I think you'll see a
difference.
