I've noticed (since I got an HDTV) that the audio delay Digital vs 
Analog will even vary during a program.  I can't say which one is 
shifting, but one of them is wondering around. I observed the digital 
come from 3 seconds behind and get up to 1 second ahead before falling 
behind again, all during the same network program. It seemed that most 
of the shifting occurred around the commercial breaks. I was unable to 
confirm if it was creeping inside the program segments.
