    Is that from a sync separator IC? if so link to data sheet.

    I am sooo very sorry for all the "commotion" I caused.

    I just discovered the error. I was using IC LM1881M, but then changed to IC LMH1981. I was wrongly under the impression that this new IC would produce one Vertical Sync per frame ... NOT so!!! Each field has its own VS.
    This explains the miscount of the counters .... they counted correctly after all.

    THANK you to ALL
