XM Radio has two channels, XM Pops (866) and Fine Tuning (855), that are broadcasting in 5.1 surround to its members. I do not believe that Directv is transmitting the 5.1 signal since my Denon 3802 does not recognize a 5.1 signal. Can anyone confirm this and is there any chance that we could get this in the future. If not, that is too bad because they play music recorded to DVD-Audio and SACD.
