Here is the simple procedure "pseudo_to_true", which I neglected to post
along with the write_mpeg procedure:

FUNCTION pseudo_to_true, image8

s = SIZE(image8)
IF s(0) NE 2 THEN BEGIN
MESSAGE, 'input array must be 2D BYTE array.'
RETURN, -1
ENDIF

width = s(1)
height = s(2)

; Load current color table into byte arrays
TVLCT, red, green, blue, /GET

image24 = BYTARR(3,width, height)
image24(0,*,*) = red(image8(*,*))
image24(1,*,*) = green(image8(*,*))
image24(2,*,*) = blue(image8(*,*))

RETURN, image24

END
