Help with garbled voices when playing back 7.1 DTS on 5.1 DTS receiver

[Squisher]

I just purchased a blu-ray player and I seem to be getting a garbled kind of echo from the voice track when I select 7.1 DTS on movies and play it through my Nakimichi AV-10 receiver which is only 5.1 DTS capable. This is not the case if I play movies that are Dolby Digital. Is this an artifact from what I'm trying to do or is something broken in the DTS decoding section of my receiver or possibly something in my new player? By-the-way I'm using the digital optical cable from the blu-ray player (Panasonic BMP-BDT 100) to the receiver. Back when DVDs had the DTS option I don't remember having any problem, but now that I've purchased a blu-ray player I'm trying to figure this out.

I'm a bit confused, why not select 5.1 DTS since that's all your receiver can handle? Won't that solve your problem? I don't select the 7.1 DTS on a movie soundtrack even though my H/K does 7.1 because I'm not using the extra rear speakers. I do use dipoles for my rears, and I could hook it up that way, but I like the added surround presence in 5.1. Normally, 7.1 adds 2 REAR CENTER channel speakers, like 6.1 adds 1 REAR CENTER channel. So I would assume your receiver is adding and mixing the 2 missing rear center surround channels to the front center channel which is causing the garbled echo effect.

In the 2 movies I rented it wasn't given as an option. It was either 7.1 DTS English, 2 channel English, or a multitude of languages in 5.1 DD.

Heck, I hadn't seen anything that offered DTS in years. I wondered where it went. Now I know, you blu-rayers were keeping it all yourselves.

Not really sure how 7.1 vs 5.1 would be an issue. Voices almost Always come from the center channel or from L/R.

It is when the receiver has no idea what 7.1 is and can not properly handle the signal.

just curious what movies these are. not many movies even have 7.1, and every one that does have it that i have personally seen, also has a 5.1 track on it. i probably own like 30 blurays and none of them are without some sort of english dd/dts 5.1 soundtrack on them.
