Is anyone out there getting this same problem. Shooting with Canon XF300, legacy and new footage on win 7 64 bit- Old HPZ400 workstation w/XEON and HP Z230 Workstation new computer w/i7, MC 6 and MC 8 respectively. MXF AMA plugin updated July 1 '15. Canon and AVID have been trying to help - Canon suspects Media composer, AVID suspects Canon footage. Problem persists. The only workaround that exists is converting MXF to DNxHD. Not an option for Legacy projects. Help please.
