If you access the Internet through a firewall or proxy server, you will need to make the following changes.

Note: If you are accessing Yahoo! Video from a corporate network, and you don't have your proxy server information, we suggest you check with your company's IS department for information on the proxy server you may need to use to view Yahoo! Video content.

Windows Media Player 7 or higher

1. Open Windows Media Player.
2. On the menu bar, select "Tools" and scroll down to "Options."

4. Under Protocols, if HTTP is not checked, try checking it (it should be the last Protocol you try enabling).
5. Then click "OK" to close this window, and "OK" again to close the Options window.
