Both OTA and FiOS and on 2 different sound systems.
Last night during Wheel of Fortune (I never watch this, but had it on last night so can't compare to other nights), there was rear audio. I'm assuming that is because it was 2.0 (at least I'm assuming they aren't natively 5.1) and WVECs equipment converts to 5.1 and sends the signal that way.
Anything that originates in 5.1 (primetime programming, NBA games, etc) does not have rear audio.
I should mention that once they discovered that they were sending 5.0 and not 5.1 the audio became remarkably better, just w/o the rear ambient audio you get with all other locals.
