lip sync problem new HT

[prelag]

I just setup a new system.

Samsung LN52A750 (AMP turned off)
Onkyo TX-SR607
Polk RC65i
Polk RC85i
Polk CS1
Polk PSW10

I have my Samsung connected via HDMI out to my Onkyo. My PS3 connect via HDMI in to my Onkyo. I also have my Direct TV box connected to my Onkyo via HDMI in.

I get lip sync audio problems while playing blu-ray movies and watching Directv.

PS3 sync problems are just a bit off, and vary movie to movie. I have my AV Sync set to 40ms, which helps a bit.
Directv sync audio problems are worst and vary channel to channel.

I have tried the Onkyo built in "auto sync" feature with little results.

Do I have something hooked up incorrectly? Is this normal with Surround Sound? Is there any fix? It's extremely annoying, and makes it hard to watch movies / shows without noticing the audio / video being off.

Also, I had no sync problems when I was just using my TV speakers.

Any help would be much appreciated.
