You might turn off the video processing on the Denon and see if you get more consistent video delay issues across formats.

Thanks again for your help.
I believe the X1300W just passes video without processing - at least there are no processing settings in the menu. I experiment with a few things last night:
(1) Moved the Apple TV to the Blu Ray Port, which was empty and second closest to HDMI output (this is based on a user recommendation and a support article provided by Denon)
(2) Bypassing and/or turning off ARC support completely (i was using it to get audio from the onbaord Roku Apps
(3) Soft Reset of the Denon, followed by complete reboots of all connected devices.
(4) Turning off Dynamic EQ
(5) Increasing dialogue volume +2 db
The ARC changes made no difference whatsoever. However, some combo of the others has helped a lot. I still have a delay, but I can set a 80ms delay which improves DV material good amount but has an almost imperceptible difference on the other content I watch. I note, there is still a delay as DV material needs an additional delay to be perfect. The actual amount of the delay adversely affects the other material way too much to be permanently set.
My next efforts are to replace the cable with the Apple recommended cables. I do not think this will change anything since I am using good cables over a short distance already, but at least I can try. I am also considering either re-running audyssey - any chance that would make a difference?
