A lot of cable channels don't carry DD. I frequently see my preamp switch from "Dolby Digital" to "DD+ProLogic" when channel surfing.
I only watch HD cable channels, and my receiver almost always says "Dolby Digital" except during some commercials, then it will switch to "Stereo". Again, that's on HD channels, SD channels are probably often not broadcast in DD, I'm not really sure on that.
