Becuase Voom went belly up ( I am still in mourning) I decided to go with Dish Network. I noticed that most of my channels are only in 2.1(?) now instead of the 5.1 I enjoyed with Voom. Is there a setting I am missing or something? My receiver is set the same. It used to process the Voom channels very nicely and now it seems all my sound is in the front channels.
