I just noticed I'm having problems watching NBC Today in HD on my XBR...the audio doesn't match what is coming out on tv...I think the audio is a bit earlier...commercials on this channel are fine though...other channels are fine...going crazy trying to correct this...is it done on my Denon Receiver or on the tv...tried turning the tv off and on again...unplugged the power and the DirectV receiver reboots...how can this be unless it is a problem with NBC...I don't have the problem on my Samsung LCD tv in my bedroom...not using it through any audio system...just the built in speakers...so right there, something must be hooked up wrong on my home theater system...any thoughts would be greatly appreciated.
