Simply we can say Dolby digital is 5.1 sound and Doby digital plus is 7.1 sound.And sound bit tare will be higher comparing to dolby digital.That means we can get more powerful sound in DD+.That is the reason TS has enabled DD+(of course some are fake).
2nd thing it is advisable to watch in PCM sound only who are not having HT.If they put in DD or DD+ mode then it will go to surround mode and the voice wont come properly because there is no central speaker to catch voice.it is not the TS falut it is our fault only.In fact sound is coming perfectly in all channels in DD+ in HT.we can't catch it in normal TVs.

As per Wiki

Dolby E

Up to six channels, such as a 5.1 mix, can be recorded as 16 bit Dolby E data. However, if more than channels are required, such as 5.1 plus a stereo LtRt, the AES3 data must be formatted as 20 bit audio.


It is very important to ensure that a Dolby E stream is never played through monitors or headphones without decoding. Undecoded Dolby E data will be converted to analog as full scale (0 dBfs) digital “noise” that can easily damage loudspeakers and/or hearing. Unambiguous media labeling is essential to avoid this.

Dolby E never reaches home viewers as it is intended for use during post-production when moving multichannel material between production facilities and/or broadcasters. It is decoded prior to transmission.

Though it shows Dolby E, I guess we are not even getting. Only the below is used in our case.
-----------------------------------------------------------------------------------------------------------------------------------------------------

Dolby Digital Plus, also known as Enhanced AC-3 (and commonly abbreviated as DD+ or E-AC-3, or EC-3)

Dolby Digital (AC-3) and Dolby Digital Plus (E-AC-3) bitstreams via an IEC 60958/61937 (S/PDIF) interface. However, the S/PDIF interface has insufficient bandwidth to transport Dolby Digital Plus (E-AC-3) bitstreams at the 3.0Mbit/s datarate specified by HD DVD; lower datarates are possible.

Dolby Digital Plus may be transmitted across HDMI 1.3 or newer, according to IEC 61937-3.

Dolby Digital Plus is seeing increasing use in digital television systems, particular in cable and satellite systems, as a replacement for Dolby Digital. Many such applications don't take advantage of its higher channel count or ability to support multiple independent programs; instead it is used as a higher-efficiency codec than AC-3.
