I did the update. I noticed the headset problem I had went away - the clicking sound I would hear through the headphones when my cable box and tivo are paused is no longer an issue. However, there's still bleed-through coming through my speakers when a headset is plugged in. (You have to crank it up, but it's pretty obvious.) Keep up the good work guys.
