	You're dreaming. The 300K file contains nowhere NEAR the
resolution as the 24 bit Toaster image. The catch is that the
NTSC display is only slightly better than the DCTV image so the
difference is hardly noticable. HOWEVER, if you compared the DCTV
conversion of the 24 bit Toaster file with the output from an RGB
24 bit frame-buffer, you would notice the difference.
	Be sure that DCTV is slightly worse than NTSC, I belive
mainly in vertical resolution. Although I'm not certain what is
in that 300K and what is in that 700K file, there is no way that
NOTHING is lost when you remove 4/7 of the file.
