The source player has to have DTS capability in order for the processor to work correctly. As such, if your EAD is not DTS capable, you will never get DTS out of the Chiro unit. Sean
Get your hands on a DVD set up disk. I use The Ultimate DVD Platinum edition. There are a series of audio set-up tracks with DTS and Dolby Digital test signals. I have the Chiro 5.1 & C800 combo and it plays DTS VERY well. Don't forget that you must select the DTS sound track manually on most DVD's. It's usually in the main menu.
The Chiro combination is one of the best I have ever heard. If you do have a problem with your unit, I have the name and address of the guy in California that repairs Chiro gear.
