[SOLVED] 5ds(r) - mov video not opening in Canon Movie Utility 1.3

I can open the .mov Videos without Problems with Windows media Player (win 8.1/64bit)
but...
I cant open it with Canon Movie Ultility 1.3
(I cant open it with Magix Pro X 6 - no error on Import, but Video remains black, Sound is hearable)

is there any conversion mandatory for Canon 5ds(r) Video files?

I used PAL, FHD 25.00P ALL-I
timecode record run
Canon Firmware-Ver.: 1.0.1 R

Liebe Grüße
Georg
