Thanks, Danne:
So, a re-statment of the problem....at 29.*** fps, I got 4.5 thousandths of a percent pink/corrupted frames.
I re-ran what I think were my original settings, but turned on Global Kill. But, I did an apple to apple comparison with only one change, ran on a 130MB/s card, compared to a 170/MBs card.
130....39.** write speed, red camera, 8milliseconds Idle (available buffer ?) Didn't look for corrupted frames
170....45.7 - 45.9 write speed, green camera, 4% - 5% Idle (available buffer ?) ZERO corrupted frames
Problem solved, thanks...I'm learning a number of things per day because I am delving into all the settings and modes of ML. Oh, I ran these 2 tests with only 160 on the SD overclock and 12 bits depth. I'll probably change the bit depth and overclock later today, re-run just to see how the write speed changes...
