There are 7.1 receivers because having 7 speakers can create a more enveloping sound field with speakers at your front, sides, and behind you. There are currently no 7.1 discrete recordings but that doesn't mean you can't get 7.1 sound.
Receivers have many options for expanding 2 channel or 5.1 channel mixes to 6.1 or 7.1. 'All channel stereo' modes take 2 channel mixes and expand them to 5, 6 or 7 channels. Dolby Prologic II expands 2 channel to 5.1. DPLIIx expands 2 channel analog or digital to 6.1 or 7.1 and can also expand 5.1 to either 6.1 or 7.1. DPLIIx can be layered on top of DTS 5.1 or 6.1 to create 7.1, etc...
So the number of discrete channels recorded on a disc has only a limited relationship to how many channels you can get for playback. There are no discs in any format that contain 7.1 discrete channels, but that may change in the future so having a 7.1 receiver is useful to be ready for future 7.1 formats should they ever arrive. A 7.1 receiver is also useful now if you want to use the processing modes described above to get 7.1 sound from 2,5.1, or 6.1 sources. Additionally, many 7.1 receivers can be configured to play 5.1 in the main room and use the other two amps to drive stereo speakers in another room. Lots of good reasons to choose a 7.1 receiver in my opinion.

There is EX which is 7.1 and DTS ES which is 6.1 or something like that. I have a Sony 7.1 reciever and there are movies in 7.1 and 6.1 cause I have seen/heard them. But only a few. Dont you just hate it when someone writes like thay no what their talking about but don't have a clue.

Yes, I do and I would put Dan L Fedric Jr in that category. The 'EX' you are talking about is Thx Ultra 2 and it is a matrix decoding format, just like the others described. There are no discrete 7.1 movies in any format! Do some research on your own before making a fool of yourself.
So there are no 7.1 DVD titles out there. Whew, I almost thought I was missing some titles with all those 7.1, 8.1 and 9.1 receivers out there.
I was about to ask if there are 7.1 DVD players as well. Wouldn't make much sense playng a 7.1 DVD on a 5.1 player that won't recognize the format, would it? Or maybe the S/PDIF will just pass it on and wouldn't care less how channels there are?

Hi,
My DTS copy of "The Haunting" shows 6.1 Discrete on the face plate of my Denon 5800/03.
I can't remember if the 5800, prior to the upgrade had the capability to recognise it but the back of the DVD's box says that it's a decoder issue and based on what you have will play in 5.1/6.1Matrix/6.1 Discrete.
I have purchased as many of my 150 dvd's in DTS as possible. The Haunting is the only one that I remember was discrete. I've written to DTS for a list to-day. Let's see what they say.

PS I ran into this thread from a Google search
This is Dan Fedric again and what I was saying is that their are DVD's that are 7.1 movies when my receiver is on auto detect and an ex or 7.1 movie is playing my dolby digital blue light comes on and instead of the receiver showing 3/2.1 it show somthing like 7.1 ex and the two rear center speakers magicly start working and it is awesome. I would call that a 7.1 movie you on the other hand are trying to make people think that this does not exsist.
And I'm here to tell you it does weather its matrix or decrete the format does exsist and it sounds really good and you do need a 7.1 receive to hear it.
Are there any DTS 7.1 tiltles on dvd ?
7.1
