So, i've tryed to set CVI as 8 bit and separate sync format, but still, using vid_datavalid as vcc it does't work.

Output from the video conerter, in 4:2:2 YCbCr there are only

TD_VS

TD_RESET

TD_CLOCK (@27MHz)

I REALLY don't know how to interface them correctly with the CVI.

Any hint wold be precious..
