Scenario: After deleting a recording on the DVR, I drop down to the History list and press the right arrow to enter. Then the menu portion of the screen goes black, leaving only the small LiveTV screen visible. Left arrow does not back out. Pressing 'Exit' button brings LiveTV back to full screen.
Frequency: Infrequent. From several times a day to once in several days.
Not a huge deal, but it is annoying.
