ADV7611 1080P50

Hi,

          I have capture the video of 1080P60 and 1080P30. But when I put the 1080P50 into the ADV7611, the ADV7611 output is not very well. The V signal is sporadic。 And if i read the register from ADV7611, HPA have be detected, but TMDS_PLL_LOCKED is 0, TMDSPLL_LCK_A_RAW is also 0. The TMDS clock can not be measure from TMDSFREQ and TMDSFREQ_FRAC.   The edid of adv7611 have be tested OK by another board(It is DM368's platform). So I do not doubt the edid. 

         By the way, the Gopro3 have be tested OK, but the sony  DV and camera RX100M2 is not OK. So can you tell me what should I pay attention ？
