Okay, first of all thank you for taking the time to read my post. I currently have a Pioneer reciever and a HD Mits Sat receiver. everything is hooked up with optical lines. when I play a DVD with Dolby 5.1.. the Pioneer actually reads out, "Dolby Digital", however, when I watch a DD Movie on Directv, it wont give me that read out; however, it does ready out, Digital. How can I tell if I am getting Dolby Ditial? Is it just that the Pioneer does not get the same signal to show "Dolby Digital" yet I am listening to it? any assistance is greatly appreciated.
