Enable MPEG-4 start code lookup offset
MVIDIPv4 units sometimes develop offset start codes in the MPEG-4 video stream. As a solu-
tion, the MPEG-4 start code lookup value must be increased so that the video stream will be
found in Omnicast. This advanced setting must be modified on the Client and Server machines
for proper archiving and video decoding.
