I am having a problem with lip synch on my Sony Bravia TV with signal from my Shaw DCT3400 box. It was much worse previously and I corrected it somehow but now cannot find the instructions in any of the manuals relating to how to delay the audio signal to compensate for the slower processing time of the video signal. I cannot remember if the adjustment was made in the TV or in the PVR. Can anyone help? Is there such an adjustment with the DCT3400, or is the adjustment made in the TV?
