I have a barco data 808 and the blanking does not work for top and bottom. So far I only have about 40 dollars invested in the unit. My question is if I get a line doubler would that help? I have a 16:9 screen and I have read the DVDO iscan will convert 3:2 images to 16:9. I wonder if it would also compress the image to elliminate the 4 white rectangles that flash off and on above the picture with some of my DVDs. Anybody know?? PS I intend to get one eventually...will get it quicker if it helps this problem.
