Has anyone else had a problem hearing anything besides the audience during the Tonight Show and Late Night w/ Conan O'Brien for about the last week or so? I'm watching through the East Coast HD feeds and the center channel audio just isn't there. I normally watch just on my tv using the hdmi w/ a highest volume of 20, but mostly around 15. Now, I have to listen at nearly 30 to hear anything besides the audience. I turned on my audio receiver just to confirm the problem. The center channel is showing up as having a signal, but nothing is coming out of it. I know it's no the tivo, b/c I've checked other recordings and everything is just fine. I've tried to report this to dtv, but got the standard restart your tivo response so no help there.
