Ok guys, I pulled out my "Home theater in a box" that I got about a year ago. Until I get my axiom system I will be using this system. Now here is the problem. I hooked everything up and I had FoxHD football on which I know is broadcasting is Dolby 5.1. My home theater in a box will only play it in Pro Logic 11 though. I can only get the Home theater in a box to play dolby digital when I put in a DVD. What am I doing wrong? Do I not have something connected? I had this system at my old house and the Dolby digital 5.1 worked fine.

I have a cable running from "Digital audio out" on my cable box to "Audio Coaxle in" on my home theater in a box reciever.

that is the only thing that is connecting my cable box to my surround system. should i have something else connected? please help, i am beyond stressed out, been working on this damn thing for 4 hours when im supposed to be watching my football!!!
