• If you have a slow connection, the video may take a little while to load. With a fast connection, it should start playing withing a couple of seconds.
• If you are having trouble seeing the video, click here to download the newest version of Quicktime.
• A sure sign that you need a new version of Quicktime is if you are hearing audio but seeing a blank screen.
• If you're having problems but the installer/updater tells you you already have the newest version of Quicktime, try uninstalling Quicktime and then reinstalling it from the site; this may fix your problem.
• To download the video to your desktop, right-click on it and choose "Save Target As" [on a PC], or hold down the "ctrl" key while you click on it and choose "Save Link As" [on a Mac]. If you don't like Quicktime, this would allow you to try playing the video using some other players:
  • It should play in iTunes. Click View > Actual Size if the screen looks tiny; move the mouse over the bottom of the video to see the controls (Play, Pause etc.)
  • It should also play in the very versatile VLC Media Player. Click here for more info on the VLC Media Player, and download it if you like it.
• If you continue to have problems, please email Hartmut with a specific description of your problem (e.g. what error message you're getting, what browser & operating system you're using, what you tried to do to fix the problem, whether you've experienced a similar problem in other contexts, etc.)

How to INSTANTLY hide the controller in Quicktime, so it doesn't cover parts of the movie:

If you move the mouse onto the Quicktime Window, the Quicktime controller appears, which is convenient but can also be annoying since it often covers up the text at the bottom of the video. If you stop moving the mouse, the controller eventually disappears, but only after it's annoyed you for a couple of seconds. There are two ways to make the cursor go away instantly:

• 1. Move the pointer out of the movie frame.
• 2. Click anywhere in the movie frame
• If you've paused the movie, only Option 2 (clicking in the movie frame) will work.

How to pause the movie and control movie playback.

It's important for you to be able to pause the movie when you need time to process/think about what you've heard, and to be able to go back to view some parts multiple times. Here's how:

• To show the playback controls, move the pointer anywhere over the movie.
• To go to a specific point in the movie, drag the playhead (the small circle) in the timeline.
• To step through frame-by-frame, press the Right Arrow or Left Arrow keys on your keyboard.
• To pause a movie using the keyboard, press the Space bar.
• Jump to a chapter by clicking the chapter button (an icon consisting of four little squares themselves forming a square), and then select the chapter you want. Drag the window to enlarge it in order to be able to see the chapter icons more clearly (going to full-screen paradoxically only lets you see them in a very small format).
