If the video frequently buffers, then it means that you are not maintaining a fast enough connection to our servers to watch the video at the speed you selected. First, configure your player to accept HTTP streams:

Windows Media Player 6.4:

1. Open Windows Media Player.
2. On the menu bar, select "View" and pull down to "Options."
3. In Options, select the "Advanced" tab.
4. Highlight "Streaming Media" in the window shown, and then click the "Change" button.
5. Under Protocols, uncheck "Multicast, UDP, and TCP." Only HTTP should be checked.
6. Then click "OK" to close this window, and "OK" again to close the Options window.

Windows Media Player 7 and above:

1. Open Windows Media Player.
2. On the menu bar, select "Tools" and pull down to "Options."
3. In Options, select the "Network" tab.
4. Under Protocols, uncheck "Multicast, UDP, and TCP." Only HTTP should be checked.
5. Then click "OK" to close this window, and "OK" again to close the Options window.

If that doesn't fix it, try increasing your buffering rate in the player:
