For those having a washed out image, go to the system settings on the Xbox, Console Setttings, Display, Reference Settings, then Reference Levels. Once there, choose either Intermediate or Expanded. (Whichever looks best to you.)
The audio being ahead of the video is very annoying though. It seems to drift back and forth where it will be slight and then become more exaggerated.
I have seen the sync issue on my Xbox 360 S on my Panasonic AE-4000 as well as my Xbox Elite on my 65" Panasonic VT30. So different console revisions, different AVRs, and different displays.
I hope they fix the sync issue soon. Also, the 360 has always been a disaster when it comes to color space and reference levels.
Both 360s are hard wired on a gigabit LAN, connected to a Linksys E4200 router on a 25Mbps connection. Never had any sync issues with Netflix on either PS3, either Xbox, phone, iPad, computer, etc.

Motorola 7100-P2 set top gives a far better picture and sound on my 7.2 audio and sony projector system through my Pioneer AVR via HDMI.
Even though the 360 is outputting a AC-3 signal, it is just two channel Dolby Digital. No center, surrounds or LFE.
