Audio-Sync Issues

[Stang68]

Hey everyone,

So I've had my Sony BDP-S360 for about 10 months now and I like the way it performs. However, on some Blu-Rays the audio is out of sync. The picture seems to be ahead of the audio by a few milliseconds. Now, the S360 has audio-sync options but they only work if the audio is BEFORE the picture. This issue is happening with "The Matrix", "300", "Iron-Man", "Inglorious Basterds", etc, so it's not just one film. Does anyone have any suggestions as to what I can do to solve the problem?

PS: I do have the player hooked up to Bose Cinemate speakers. Could that cause the delay in the audio? Should I look into changing the connection?
.
Thank you!!
