If I turn my iPhone (4s) sideways to watch a video, then bring up the menu on the right, if you have all 6 options enabled only #s 2-5 (Remote, Movies, TV Shows, Music) fit. The first (Home) and the last (Collections) are off the edge. That in itself isn't a problem, you can swipe up or down and see them but the menu snaps back before you can click them.
The left (settings) menu has a similar issue. It starts with Change User and Server Config, but lets you swipe up to get to General Settings. You just can't get to Customize without it snapping back.
