Something you could also try, for kicks, would be to enable the AV Mode "Game" on the Sharp. (Not saying to keep it like that permanently, but I'm curious to see if your A/V alignment magically resolves once you put the Sharp in Game mode.)
I can adjust the lip sync on the Denon to add an audio delay, but it is not an easy task to do this with just my eyes and ears. Is there a better way to do this than just winging it?
There might be one way to test this. If I hook up the PS3 to the TV with HDMI, and again the PS3 to the Denon 1613 with TOSLINK, I can output sound on both cables. What this does is create an echo between the TV speakers and the AVR speakers. I can then use the Denon's delay feature to eliminate this echo. This should tell me the TV video delay for that particular mode/content. I think I will do this test and report back.
I wish there was a chart out there that showed what the delay is for the Sharp in different modes so I don't have to do my own R&D. Maybe I can make one.
BTW, I tried "game" mode at your suggestion and it worked pretty well. I felt like it was not 100% perfect, but your mind plays tricks on you when you try to get down to that level of accuracy with just your eye. I was using movie mode previously with what I thought were all motion functions turned off. Apparently this was still producing more delay than the game mode.
I don't know what type of impact it has on the video switching from movie mode to game mode. I will need to research this detail more.
I am starting to suspect that delay changes depending on the type of content I test. With that in mind, I should disclose that I am using a Blu-Ray version of Ironman to do my testing for this thread. This content shows "Dolby HD" on my Denon 1613 - something my Denon 1601 was not capable of decoding [5.1 was the best it could do].
