In the client code I set param.analyse.intra = X264_ANALYSE_I8x8, which 
does block i4x4 but doesn't block i16x16, which is why I had to patch 
libx264 itself.

Because Avid decoder assumes there will be exactly 10 slices and each 
slice will have exactly the same number of macroblocks. Without this 
patch I saw artifacts such as missing macroblocks at regular intervals.
