I also commented on this sync issue in "D*Upgrade Woes".... my Sharp LCD may be causing some of the sync issues- have seen this on LCD, plasma, etc. any digital display. I suspect the higher resolution signal from my H20 makes it worse. Before I
got HD, SD did it too- if I used S-Video out of sat rcvr. Composite showed little sync issues, but could be the poor resolution hid effect. I plan to try an HDMI cable, as described in my post, to see if that resolves. In the H20 manual, for sync issues they suggest changing channels, or selecting "list' and "exit" on the remote (this seemed to help somewhat), and last, to reset the receiver. Ultimately, the issue is video delay caused by the display, but could perhaps also be the H20. If nothing else works, I plan to add a digital audio delay line to sync the audio to picture. It might have to be a professional model to get one with fine enough adjustments. Hope that helps. I will post updates as I go through them.
