Mike,
We were trying unsuccesfully to load a setting (from the Cine Alta site, loaded via PC burner) using a 64 Meg stick (not Sony) to our F900, I called Sony maintenance, the tech told me that our problem was that the stick had too much memory. He said that 16 megs or less would only work in an F900 and that you could only record one set-up per stick. So,,,, I wonder what the official working practise is. I spent the rest of the day, trying to source some small 16 meg or less sticks, not an easy task.
