So far most digital TV is still DD2.0.
HDABC and HDFox have network originating programing available in DD5.1. (not local programming)
CBC-HD and Radio Canada have some programmes in DD5.1
HDNBC has new prime-time HD programmes in DD5.1, although Detroit currently has issues and doesn't do DD5.1.
Movie Networks like HBO have many movies available in DD5.1.
HDPBS has a very few of its programmes available in DD5.1.
HDCBS has some of its programming in DD5.1 (it used to be only specials, but now there's some more)
See --> This Link for programmes in DD5.1 (http://www.dolby.com/consumer/home_entertainment/tv_listings.html)
In order to receive DD5.1, you, of course, need a digital STB that has a digital audio output (coaxial or Toslink). Your A/V receiver also needs to have the equivalent digital input and a DD5.1 decoder. Such a receiver typically has "Dolby Digital" and/or DTS emblazoned on it.
Some additional notes:
1. Some Channels often have DD5.1 signal, but the audio is not properly encoded - the dialogue doesn't come out the center channel for example, coming out the LF & RF. Sometimes the dialogue is missing altogether.
2. HD ABC is usually DD5.1 all the time (if the affiliate has DD5.1 capability), but only Network-originating programming is DD5.1, so the dialogue won't be out the center channel with local programming typically with sound only out the LF & RF speakers. Sometimes the sound comes out the rears, instead. I call this "improperly encoded DD5.1". It happens a lot on ABC, as well as Seattle NBC (Jay Leno).
3. DD5.1 channels are often 10-20 dB lower in sound level than DD2.0 channels. In general, all DD broadcasts vary a lot more than analogue broadcasts regarding sound levels
On most HDTVs you cannot go "through" a TV and still get DD5.1 audio. You need to connect directly from the STB to the AVR and you need the correct settings in the STB (usually DD or bitstream). Also, the firmware in some STBs (BEV for example) is not capable of sending DD5.1 out the HDMI, so you need a digital audio connection (optical or coaxial) (This is NOT an HDMI limitation, it's the firmware that's the problem.) The optical connection on the back of the TV is for the internal tuner digital channels, not as a "passthrough".
Please PM me if you have any comments or suggestions. Questions should be asked in the forum.
