Unfortunately, I noticed audio sync problems with certain Blurays (audio came too early). I tried upgrading all my HDMI cables to v1.4 and ensuring that audio sync was enabled on both the Denon and TV, but it didn't help. I could make the issue better by manually introducing a 100ms delay on the Denon, but I didn't like that approach because that delay wasn't needed for all content. I eventually narrowed the issue down to playing 24p content that was output at native framerate from PS3 to TV. In other words, f I disabled 24p output the sync issues went away. They also went away when I tried "game" mode on the TV. But I wasn't happy with either of those appproaches so my search continued...
Today I tried plugged the PS3 directly into the TV via HDMI and then connecting the TV's optical out to the Denon. I eventually got it working, and it seemed to fix the audio sync issue!
But now for some reason the intro DTS-HD and THX sequences on the Terminator 2 Bluray are entirely silent. The audio in the movie itself is fine.
As an experiment, I tried enabling the TV speaker and the DTS-HD/THX intro sequence sounds came back. So the signal is definitely getting to the TV correctly and the TV is able to process it. And the problem seems to be that the receiver can't process that portion of the audio signal when it's fed via the optical input (It all worked fine when the PS3 hdmi out was hooked to the Denon!)
On the TVs audio out control you can choose between "Auto" and "PCM", and I've tried both. I've also tried having the Denon input format set to "Auto", "PCM" (the only other choice is DTS). On the Denon, the display shows no audio format text until after the THX sequence has ended, and then it displays "Dig" and "PCM".
Any help would be greatly appreciated!
