I had one of these a while back, back when the XBox was first released. Unbeknowst to me at the time, there was a problem with these units not passing on the 5.1 sound to your receiver. I went through a couple before giving up on the whole XBox experiment. As soon as the XBox went down in price (the first time) I bought it again, but this time overlooked the MadCatz Ultra and bought the Microsoft unit, once bitten, twice shy as they say. Hopefully, the MadCatz unit you bought is (should be) one of the working ones. Comparitively speaking for what you get in the MadCatz Ultra Kit as compared to the Microsoft Pack, the MadCatz is a bargain! Enjoy!
