Maybe it only started to append in the last 6 month on my PS3, or maybe I am just paying more attention to that specific problem. but it seem that my PS3 is outputting the video before the audio via my HDMI setup.
let me explain :
first, I got the PS3 hooked up via HDMI to my RXV-1800 Yamaha receiver then the HDMI video out goes to my Optoma HD80 projector. sound setting output PCM audio, and video is 1080p/24hz for blu-ray and 1080p/60hz for dvd obviously.
now I also got a Oppo upscaling dvd player and a HD-A3 HD-dvd player. when I play a dvd(or hd-dvd) via those 2 players, I usually need to delay the audio on my receiver about 30ms. and this is very consistent and doesn't seem to change while the movie progress all the way to the end of a 2h movie.
now on my PS3 it seem like 75%(and it seem to append more with DTS MA sound track) of the time the video seem to come before the sound. something like maybe 20-25ms. of course my receiver can't delay video, only audio so there isn't much I can do about that. but what is even more curious is that it seem like sometimes this delay get worse as the movie progress, so when I reach mid point of a movie the delay might be 50ms, or if it was spot on at the beginning, then I will get the 30ms delay at some point. it seem like chapter skipping or selecting a new chapter via the menu fix the problem so it is definitely a playback problem.
I remember back in the era of my PS2(my first dvd player) I had this very same issue with movie getting out of sync thru the playback of a movie. It was even the reason I bought a stand alone dvd player.
Am I the only one with this problem??
