So I was trying to play UP on my SageTV box, using TMT 3, and while the preview's would play, the menu for the main movie never showed up. And when I tried to skip forward, it didn't work either. I also tried another blu-ray (can't remember - might have been monsters inc) was a no-go also. I tried using TMT for a normal DVD and it did work. I'm wondering what might cause this?
