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. >--------------------------------------- >| patrick_meloy@outbound.wimsey.bc.ca | >| 'The Outbound' BBS Vancouver BC | >--------------------------------------- -- Ethan Q: How many Comp Sci majors does it take to change a lightbulb A: None.
