Could somebody look at manpage lines 3040-3048? (filmdint filter fast option) .IPs fast=n The larger n will speed up the filter at the expense of accuracy. The default value is n=3. If n is odd, a frame immediately following a frame marked with the REPEAT_FIRST_FIELD mpeg flag is assumed to be progressive, thus filter will not spend any time on soft-telecined MPEG-2 content. This is the only effect of this flag if MMX2 or 3DNow! is available. Without MMX2 and 3DNow, if n=0 or 1, the same calculations will be used as with MMX2. Especially the last sentence. Shouldn't the last MMX2 be MMX? Otherwise we have 'without MMX2 the same calculations will be used as with MMX2'. So what is MMX2 for here?
