Need help

I've created a movie and took it to post production. Everything is good until I try to export the movie, when color gets totally screwed up. There are gray stains all over the place,and general quuality is very shitty.
Any ideas?

Perhaps you can take a screenshot and post it here?

Have you mocified TM ? Sometimes textures are getting screwed up - when you add Sets, Props, Costums, etc.... I had also such a problem in the past. If yes, try it with the original DATA file without any mods. (I hope you backed it up).
