I had this b/4 with the D650 deck. There is a polling.txt file u can put in a folder to cure it. I can’t remember @ the moment. Email me on Mon. and I’ll look on our system for the answer. chris@videoatlanta.com
U should check out the AJA forums – they have boards/cards that will out-put your HDV and HD without a prob.
They have low-cost reliable products with great support.
