Thanks Jim......nice that you have the ability to send the OTA audio signal from the tv using arc instead of an additional optic cable. I've been reading up on this a bit today.....it looks as though ARC is intended for that type of convenience as opposed to fixing the lip sync issues that in my case appear to be affected by different channels as well as sources.
