The other night while watching The Cable Guy on HBO (DD), the audio would drop out for a split second several times throughout the movie. Following this I watched Cast Away on the same channel, also in DD, and did not have any audio problems. So, for kicks, I switched over to the other HBO feed and watched a few minutes of The Cable Guy again to see if the problem returned. Sure enough, the audio problem started again on this movie. I have also noticed it on Shrek. There are no picture problems. It only seems to happen in DD. Could it be something about certain movies? Any ideas?
