Whenever I tune to channel that is in dolby digital it takes up to 20 seconds for the audio to drop in. What's more frustrating is that when I'm watching something recorded in dolby digital and I use the fast forward command (or any command for that matter) and then hit play, it can take up to 20 sec. for the sound to come back again. Is this normal? I noticed no one else has been complaining about this problem. I have my system set up as follows which may or may not contribute to the problem. HR20 to my Samsung AMP/DVD player via HDMI, then from AMP/DVD player to the TV via HDMI. I would think that if anything the audio should play before the picture not the other way around.
