Have you tried this from pg. 73 of the manual?

5. A/V Sync: Allows you to add a slight delay to the audio so it is synchronized to the video. You may
use the LEFT/RIGHT ARROW buttons on the remote to decrease/increase the audio delay. The delay
can be adjusted in 10ms steps and within the range of -100ms to +200ms. The delayed time will be
applied to all output terminals including HDMI 1 and 2, Coaxial, Optical, and 7.1 outputs.
The actual audio delay effect might be different for each of the output terminals due to the
different audio process algorithms and signal paths used for each output. Please adjust this
setting based on the actual output terminal in use.
The negative adjustment values are for cancelling out the audio delay that the player
automatically applies. Depending on the video source and the time it takes to process the
video, the main decoder chip automatically applies an audio delay in order to optimize audio
video synchronization. The negative manual settings reduce the automatic audio delay, while
the positive manual settings apply additional delay. Any negative value setting beyond the
player's automatic delay will be treated as completely cancelling the automatic delay. For
example, if the "A/V Sync" value is manually set to -100ms and for the current video source
the player applies a 70ms automatic audio delay, the final result is that the 70ms audio delay
gets cancelled and the audio is not delayed at all. It is not possible to put audio ahead of video
using this setting.
For content sent through HDMI IN, the "A/V Sync" adjustment only works with positive values.

Was wondering if there was some sort of setting I was getting wrong on both players.
