For example, one channel might send 5.1 but only have sound in the L/R channels. Do you get the same result on all channels?
#2. In the lipsync menu, change it to Manual instead of Auto (Auto rarely works on any AVR). Then see what you're getting with the manual delay at 0ms, and increase it from there. But you will never have perfect lipsync all the time due to errors at the source. TV is the worst, sometimes they transmit the signal with huge lipsync errors. Blu-ray is more consistent but you still get some discs with lipsync errors.
Thank you for the replies!
#1 - The center channel would not work on any sound field, on any channel, for anything. It was like the center channel was not even plugged in. It was showing it was on, on the AVR front panel, but no sound. When I woke up this morning, everything worked fine and have ever since. IDK what the problem was!!
#2 - My problem is not sound advance, but delay, meaning I need the sound advanced. If I use the lipsync function on the AVR, it makes it worse. Is there any way to advance the sound or delay the picture? I did find that if I run the signal from the DVD straight to the TV, then use either ARC or an optical cable for the sound back to the AVR, it works perfect. The only problem is, my sound is then PCM and if I want to look at the on screnn menu, I have to change the source on my TV. UGH.
I do not have any issues AT ALL with my HD cable box and lipsync issues. It is perfectly timed. I have a pretty old Sony 3D blu ray player. I may just upgrade. Any suggestions on a new blu ray player?

My problem is that the settings at "0" still sometimes give delayed audio to the video so it would seem I would need to go in the other direction, which is not an option. My setup is using the HDMI ARC, which I thought offered Automtic LipSync compensation but it doesn't seem to always work.
This is my exact same problem, except with my DVD/blu ray player.
