I recently updated my 805's firmware from 1.01 to 1.08 and also updated my HDMI firmware from 1.00 to 1.01. I created a post HERE that outlines the changes/improvements I noticed, but for those who don't wanna check out that link, here is the portion that pertains to lip sync:
I have been a big complainer about lip sync issues with the 805. I have not done any actual delay measurements, but I can say that it appears the delay has *improved*. It is still there, but it seems Onkyo was possibly able to write more efficient firmware that reduced it a bit. My favorite test is "The Pianist" chapter on the HD DVD "The Pianist" when he is trying to open the can of food by banging the top of the can quickly with fireplace tools. From my memory of doing prior viewings of that scene, it seems that the delay is better. It still appears that lip sync delay is the worst with lossless audio tracks. I confirmed this by playing both the TrueHD and DD+ tracks on "The Pianist" track. TrueHD did appear to have more delay. I'll continue to monitor this, but it seems to be reduced enough that it is close to a non-issue in my setup.
Has anybody done any actual measurements to see if delay has changed/improved with firmware revisions? I do find it interesting that talk about lip sync issues in threads like this *and* in the 805 thread both seemed to slow down as time has passed. This seems to indicate that perhaps as time passed people were purchasing 805s with newer versions of firmware installed that were improved regarding lip sync delay as compared to earlier purchased 805s.
