If the material you are trying to watch frequently buffers, then it means that you are not maintaining a fast enough connection to our servers to watch our content at the speed you selected. Yahoo! requires a minimum connection speed of 100kbps to watch video. You may need to lower your bandwidth setting. On the player, in the upper left-hand section is the "Preferences" link. Clicking it will present you with the different bandwidth options available. Selecting a lower speed than the currently displayed speed will restart the video at a lower bandwidth setting. This should reduce or eliminate the buffering.

If that does not solve the problem, configure your player to accept HTTP streams:

Open the Windows Media Player.

• On the menu bar, select "Tools" and click on "Options."
• In Options, select the "Network" tab.
• Under Protocols, uncheck "Multicast, UDP, and TCP." Only HTTP should be checked.
• Then hit "OK" to close this window, and "OK" again to close the Options window.
