I just upgraded to Premiere from HDXL. The Premiere users manual says
"The channel banner displays the show’s title, description, ratings, and other information. It
appears whenever you change the channel. To view the channel banner while watching a show,
The channel banner can be displayed in three different sizes. Press the RIGHT arrow cycle
through the sizes of the channel banner. Press the LEFT arrow or CLEAR to hide it."
When I press the right arrow it seems to have no effect. When I did that in my XLHD it worked as expected.
