Hi, I have the ADV7280 on a custom YPbPr -> HDMI board I designed. Everything works beautifully except one problem -- the line doubler seems to create vertical "jitter" artifacts at line boundaries. I've read a few other posts on this topic, but my source is a bit different. Rather than acquiring 480i video, I'm mainly interested in converting 240p (pseduo-progressive) sources and believe the problem is with the 5-line interpolation algorithm.
Is there a register setting to force the I2P module to do a simple line double, without attempting to interpolate between multiple lines?
