some comments:

* we should not store the field name on each line of the file.
  it wastes space, and makes it harder to parse (right gruel?)

* what values do we need?
  - frame_size   (bytes)
  - header_bits  (VOL/VOP)
  - texture_bits
  - quant_type
  - quant
  - kblocks
  - mblocks
  - ublocks

motion/macroblock info bits can be derived from:
frame_size*8 - header_bits - texture_bits.

* i also reckon we should not abandon .stats immediately.
