Is anyone else experiencing very poor audio on channel n3D Olympic coverage? The background noise is normal, but the announcers are impossible to hear. Sound is normal during commercials. Switching to PCM from Dolby has no effect. Running sound through TV or Bose is the same. I have a HR22-100. I am connected to a Bose GS 3-2-1 sound system and a brand new Vizio M3D470KD 47" 3D TV.
