ADV7611 vertical sync filter

What's the difference between the V_LOCKED_RAW (0x6A, bit 1) and VERT_FILTER_LOCKED (0x07, bit 7) bits in the ADV7611?  We are trying to read the vertical sync parameters but the vertical filter bit is NOT always getting set.  Our inputs are 1080p TV or PC timings from a reputable HDMI generator.
