	Well, if size doesn't matter you can use '-K hi-res' :-)

	What I use for high quality encoding is a custom table made up of
	the hi-res Intra matrix with the tmpgenc nonIntra matrix and then
	-K file=myfile

	kvcd's claims to fame are 1) smaller filesizes (lower bitrate) and 2)
	reduced splotchiness (pixelization I think is the term used) during
	dark scenes.   The kvcd folks never made any claims about increased
	quality.

	For old VHS movies that have been run thru yuvdenoise and/or the
	medianfilter the use of kvcd tables won't really hurt the picture too
	much more.  A good reason to use the kvcd tables in this situation 
	would be to reduce the blocks/splotches during dark scenes.

	Experimentation is an important part of the process - try it and see
	what happens.
