I am having audio sync issues with pretty much all my electronics attached to my HDTV. It makes me think that I have an issue with my TV (Sharp GA470WJSB) or my Internet connection (Belkin Router, with consistent 15+mbps download speeds on wireless network).

xbox 360 playing Netflix (with wireless adapter) loses audio sync immediately.

Sony Blu Ray BDP-S570 also has audio sync issues with Netflix. It also has audio sync issues just playing a Blu Ray or standard DVD (which makes me think it's a TV issue)?

Apple TV 2 is fine to start out, but loses audio sync within 15-30 minutes. Even if i stop the video, and then go to something else, it remains out of sync (watching videos through Netflix or local files via SMB).

Please help? I think it's the TV, b/c I haven't read too many Audio sync issues with any of these devices and I have a decent internet connection.

Thanks.
