I actually haven't had time to go find the proper board and test it. You are correct, the scrolling sync issue on the adv7280 occurs with NTSC. I'm still not sure how best to fix this as the patch was Nak'd. As discussed I guess we will have to do something with a kernel param. I am told that we should not attempt to normalize default configurations among the various chips the adv7180 driver supports as it may break someone's current use of them. Tim
