Andrew,
Can you clarify? I just received a Komputerbay 64GB 1000x card and disapointed it drops out in 1920x1080p with globaldraw on. When I turn off globaldraw I am able to get up to the 4GB file recording but I have to have the audio not recorded. Are your cards experiencing the same or are you just skipping using the global draw and seperate wav file in camera? Thanks.
