Not directly from mpeg2enc, but at a later stage, with mplex.
Here are the values for -q 8:

These seem a bit low for encoding with -b 8000, isn't it? I should
probably go back to -q 7, where it hits 9200 max on one file, and it's
otherwise around 8000, plus or minus a few hundred, on all other files.
