As far as a broadcaster is concerned, a commercial (unless it has some
change in AFD or dialnorm comparable to a scene change in a program) is
just more of the program stream. It is continuous audio and video into

Could it be that since commercials are usually 30 seconds or less that they have less time to get out-of-sync than the longer program lengths?

But, if I quickly change channels and return, they come back into sync (as do the program segments).
