Long time user of magic lantern on the canon 70d.. First time poster. I'm currently using it on my 5d mark ii... Great work by the way guys. My main workflow is fine, but when I tried using MLV Lite, I get black screen when previewing on MLRawviewer.. Not being able to preview is like an arrow in the heart. Please help me or point me in the right direction. I've read to change the headers but "how" do I change it. Any help would be appreciated. 1872x1044 almost continuous I haven't let it run out.. Very impressive! I'm happy.. 
thanks
