Yet another update with small corrections of matroskadec.c and mov.c. It 
seems that for 8-bit grayscale Cinepak, the policy has been to "trick" 
the Cinepak decoder into believing the video is rgb24 and not pal8, and 
it has been working fine until I started messing with setting 
bits_per_coded_sample to 8 for 8-bit grayscale Cinepak. I've restored 
the old behaviour of using rgb24.
