Make sure that in your regular Canon menu you have selected the CF Card as the write destination. In the tool menu check the "Record func+card/folder sel." item. For some reason when I changed the ML resolution to 1920x1080, it defaulted to the SD card and I initially got a write failure. When I changed the Canon menu to select the CF card as the write destination I was able to record RAW 1920x1080 with no dropped frames using a 64GB 1000x card that benchmarked at an average of 100 MB/s.
Also, (and this has been posted elsewhere) there is a nice Mac utility called RAW Magic for converting the ML RAW video file to a series of .dng images:
