The Digital Bits response on the audio sync issue is very laughable! I almost fell out of my chair laughing. They say the more work your player has to do can cause an audio sync issue. That tells you right there that these people dont know anything about the digital format and how it works. All blu-ray players have to follow a specific specification on the format with no deviation. If you are getting audio sync issues, it can be several things:
1. Your TV's signal processing adding the delay.
2. Your receiver's processing adding a delay.
Most receivers and tvs these days have adjustments for audio sync issues.
3. If your equipment supports Lip Sync then turn it on and that will automatically adjust the delay for you. The HDMI format allows the tv to communicate back to other devices to tell it what kind of delay to expect. Then your player or receiver adjusts for the delay.
