These videos are created from high-definition sources. Therefore, they are bigger than previous videos and will take longer to download. If the videos are jumpy when playing, try these steps:

1. After clicking play on a video, click again to pause. Allow the video to download all the way before unpausing. Watch the dark gray bar to the right of the play button to see how far it has downloaded.
2. If the file seems to download slowly, you'll have to be patient. Or else upgrade to a faster internet connection. (Dial-up is the worst, and DSL is a step up from there. Your best choice is a cable modem or FIOS).
3. If the above doesn't help, your computer is probably too slow. Spend all your money on a new, fast computer and be sure to hook it up to a broadband internet connection.
