I'm buying a Leeza. I am currently using an Extron SS 220 to handle sync conversion, because my Dwin HD-700 only takes negative sync and the DTC-100 STB only puts out positive. I was going to sell the Extron because I kind of thought that the Leeza would handle that sync polarity inversion for me. But, now I'm a little paranoid and I notice that it only specifically indicates that it does this conversion during component to RGB conversion. But what about the DTC-100, which would just be in passthrough mode? Will it do this polarity conversion for me, or would I still have to keep the Extron to do that?
