When you enter the TV home screen, the information for the current program is shown at the bottom of the screen. That is, the current program on the last-used channel.

If you stay in this screen and don't have TV actually playing, if the program finishes and a new one starts, the information is not updated.

This is pretty well known and discussed in the forums, but would be nice to have it fixed.
