Here is the thread with people working out the HDMI capture. I think where its at is to have the guys that write magic lantern to get rid of the crop marks, which the way things have been going should happen soon. From what I've read, blackmagic is the more successful digital recorder with the 5d mark II HDMI output.
Super, thanks! And Telemov, thanks for that very informative one also. You all are very helpful.
