I have a zenith c32v37 TV and a harman kardon avr 230 receiver. I run a tivo, playstation, and DVD player, both audio and video, through the receiver and they all seem to have the same problem. I've read about lip synch problems where the video takes longer to process and falls behind the audio, but I have the opposite problem. My video is always ahead of my audio. I've looked through the manuals and played around in the various menus of the receiver and TV and I can't seem to find anything to correct this. Am i just missing some setting or is there anything I could do to fix this? Thanks in advance for any help.
