You understand correctly, John - the way that lipsync delay works is by "pausing" the audio signal by a specific number of milliseconds to compensate for delays in the video signal introduced anywhere in the overall signal path by video processing. You can use the "SYNC" button on the remote or the SYNC setting in each input's setup menu to adjust any video input's audio sync delay. The only case where this doesn't work is on any inputs that are classified as audio only (CD, Aux, Tape, Phono), as the sync control on those is not available.
