Help with Audio out of Sync...

Got a new TV-Sony 55EX640 and that is when I noticed the blu-ray audio is out of sync. It happens when in 24p 1080P mode. On my old Sony LCD rear projection-720P, it never happened. The audio is faster than the picture. I can increase the delay on my Onkyo AV receiver to 100ms, but it's not enough. I need about 200 to get there. If I use my tv speakers for sound, it's dead on.

Is this a common problem?

Thx.
