i think file saving problem. when over 4GB at FAT32. however RAW video are recorded perfection sometimes but sometimes not even if possible to continuos shooting it was. (well some RAW file are missing but still alive the R00, R01)
and so second problem case is like this-
does not display about the how many remain of memory card after taking a video.
it just display 29.8GB even though memory card are fill fulled it.
