I sorted it out in the end. Someone had moved where the default search method 
was initialised so I ended up doing more MV searching than previously.

BTW, there is a small bug in nsse16_mmx in dsputil_mmx.c. There out to be:

if(mm_flags & MM_SSE2)

so as to choose between calling sse16_mmx or sse16_sse2
