I just purchased a new TV that supports 3D, so naturally I had to give this a shot and see how 3D content looked. The Premiere seems to support the formats used by Comcast; I was able to view content on ESPN3D as well as 3D content served up by Xfinity VoD. However, one weird thing I noticed is that while viewing 3D content the ability to control my Tivo completely goes away. None of the buttons responds, and no Tivo information appears on the screen either (not that I would expect it to appear in 3D). Is this expected behavior? Once I switch my TV to turn 3D off then my Tivo controls return to normal.
