When clicking on the down arrow in the playlist to scroll through the shows, once the highlighted program was at the very bottom both the down and up arrow icons vanished. Needed to move mouse cursor over a playlist item for them to show up again. This is a sporadic issue and I am unable to duplicate it reliably. Also, when the highlighted program is at the very bottom of the list, clicking the up arrow to go to the recording directly above it causes the up arrow to disappear (the down arrow was not displayed since I was at the bottom of the list and stayed hidden when the up arrow disappeared). Once I was at the 2nd to last recording in the list and I clicked the down arrow this time that caused both arrows to disappear. In all of these scenarios, hovering the mouse over a different playlist item causes the arrows to return. Tried hovering mouse over "My Playlist", "Showcases" and the menu button, but none of those cause the arrows to return, only when highlighting a list item do they return. The arrows never vanish when I use the mouse scroll wheel to cycle through the recordings.
