	Oh - ok.  Last time the subject came up someone was trying to
	encode HD material.

	If you're running something newer than 1.6.2 you can, as I mentioned,
	use the "--no-constraints" and -V options to cajole mjpeg2enc to
	encoding at higher rates.  Prior to the RC2 or cvs versions there
	was a bug that effectively no-op'd the no-constraints option.

	I have, as an experiment, encoded 1920x1080 (well, actually it should
	be 1920x1088 with the vertical display size set to 1080 - but mpeg2enc
	doesn't support setting that option in the headers).

	Cheers,
	Steven Schultz
