That's hard to say. I watch the CBS 8-11 PM Monday night lineup in High Def and most of the time, the Prologic II indicator on my receiver is lit up. I do know that all of the CBS CSI programs are broadcast in DD since the DD indicator is also on and I get really good bass response through my sub while watching them, especially CSI:Miami. I also get the Starz! movie pack through Cox Cable, and they occassionally have a movie that is broadcast in 5.1.
CBS is doing DD, but it's 2.0 only--they have not done any 5.1 yet.
All of ABC's HD shows have 5.1 DD sound, but not all local stations are capable of passing it along.
I'm not sure about NBC or Fox. I do get NBC in HD from my local affilliate but have never gotten 5.1, and my local Fox affilliate (KMPH Channel 26, a Pappas Broadcasting station) has not chosen to do any HD at all yet.
If you have DirecTV and subscribe to the HD package, HDNet and HDNet movies have 5.1 sound 24/7.
Neither have I. As an example, I thought of this thread last night while watching CSI:Miami. I know for a fact I have viewed it in 5.1 DD before, as have others in the thread. Last night I look up and my Denon is displaying Pro-Logic for CSI:Miami. My Denon is always set for auto-detect and other shows that were supposedly in DD 5.1 were fine. I guess it's a crapshoot.
OT - I like CSI:Miami because I like David Caruso's "Kelly Lite" character, but I cannot get into the other CSI's because every time a see a computer display it makes me want to puke because no software engineer in their right mind would make a display that looks that way. That and the fact they can "zoom in" on a 4x4 pixel section of a photo to magically uncover a 5 megapixel 8x10 high res portrait of someone's face just kills me. If I didn't like Caruso, I'd never watch this Bruckheimer dreck.
Hey John, by crapshoot I meant the dice game not anything else that may be "delicate" in nature.:b That's what I get for having a background in the gambling business, I start using Vegas terms that have double meanings.
