  1. Why do the videos frequently pause to buffer?

If the videos frequently buffer, then it means that you are not maintaining a fast enough connection to our servers to watch our videos at the speed you selected. Try increasing your buffering rate in the player:

Note: You must open Windows Media Player separately under Start, Programs, in order to access these options.

Windows Media Player 6.4
Open the Windows Media Player.
Pull down the View menu and select "Options."
Go to the "Advanced" tab.
Select "Streaming Media (Windows Media)" and click "Change..."
Increase buffering to "10 seconds of data."
Click "OK."
Close and reopen your web browser.

Windows Media Player 7.x and 9.x+
Open the Windows Media Player.
Pull down the Tools menu and select "Options."
Select "Performance."
Under Network Buffering, select "Buffer."
Adjust buffering to "10 seconds of data."
Click "OK."
Close and reopen your web browser.

  1. Why are the videos staggering or freezing?

Whether you have a high-speed (DSL/Cable Modem/T1) or a low-speed connection (56k Dial-Up/ISDN), Internet traffic congestion affects your connection speed and/or video performance. You will get slower or faster speeds at different times depending on peak or off-peak use hours. You may get slower speeds during the morning and afternoon, but faster speeds late at night when fewer people are online. Also, treaming quality decreases as more people share a line at one time.

  1. How do I resize the embedded video?

On my PC

Increase or decrease the size of the video window:

Click on the video itslef to activate the controls. Right click on the video, drag down to zoom and select your viewing preference, anywhere from 50% to full screen.

Return to the original size of my video window:

Simply hit the ESC key.

Top

  1. I can see the video but do not hear any sound. What should I do?

Check the volume level on the Media Player in the webcast window:

Move the volume slider to the left to lower the volume and to the right to increase the volume. Click on the icon of a speaker to mute the sound. Click on this same icon again to return sound to normal.

Check the computer's volume level:

Typically this can be found by clicking the "Start" button, following the menus to All Programs | Accessories | Entertainment | Volume Control. Be certain that the left most control and the one labeled "Wave" are set 50% to 100% of the way up and that the "mute" checkboxes are not checked.

Check your speaker volume level:

The method for doing this will vary between speakers. Typically the speakers have a power switch and/or volume knob. Make sure the speakers are on and that the volume is not too low. Also make sure that your speakers are plugged in and properly connected to the computer.

  1. Why can I hear the audio but not see the video?

When Internet traffic congestion occurs, audio is often transferred before video due to the audio file size being smaller. You may only hear the video clip if the speed at the time of the connection is too slow.


Top

  1. The video quality is poor. What can I do to enhance video quality?

The problem may be with the speed of your Internet connection. Users with fast connections such as T1 lines, cable modems, and DSL connections are able to watch our videos at a much higher quality than our 56K and 28K dial-up modem users. Streaming video over the Internet requires a great deal of bandwidth, and regrettably, 56K and slower connections are not fast enough to give you the TV quality picture you may be expecting.


Top

  1. How can I quickly move through a video, or change the video size, volume, and playback speed?

Click anywhere in the seek bar right underneath the video to jump to other times in the video. This seek bar can be thought of as a percentage slider from the beginning of the video at 0% to the end of the video at 100%.

Click on >> to fast-forward.
Click on >> again to stop fast-forwarding.
Click on << to rewind.
Click on << again to stop rewinding.
If this does not work, you may need to right-click on the video and choose Play/Pause from the drop-down menu to return to the normal play speed.

Right-click on the video and choose Zoom to make the video appear full-screen. Press the Esc on the keyboard to return to normal size video.

Move the volume slider to the left to lower the volume and to the right to increase the volume. Click on the icon of a speaker to mute the sound. Click on this same icon again to return sound to normal.

Right-click on the video and choose Play Speed from the menu to increase or decrease the play speed.

  1. How do I configure Windows Media Player to improve streaming?

We recommend Windows Media Player version 6.4 or higher (version 10.0+ preferred) for optimum streaming.

Note: You must open the Windows Media Player separately under Start, Programs, in order to access these options.

To find out what version you currently have:

Open Windows Media Player.
Click on Help in the menu bar.
Click About Windows Media Player.
Download the latest version of Windows Media Player if you need to upgrade.

Following are some tips to optimize streaming on Windows Media Player:

Start Windows Media Player.
Click the Tools menu and choose Options.
Click the Performance tab.
Click "My connection speed is:" and select the appropriate speed for your Internet connection.
Select Modem (56 kbps) or a lower speed if you have a 56k dial-up modem connection.
Select DSL/Cable (256 kbps) or a higher speed if you have a high-speed connection (DSL, Cable Modem, T1, etc.).
Click OK.

Note: You can change these settings at any time.

Optional advanced settings:

Click the Network tab and select all the protocols: Multicast, UDP, TCP, and HTTP.
Click the Player tab, select "Enable automatic codec download", and choose how often you would like to upgrade (i.e., once a day, once a week, or once a month).

  1. In Windows Media Player, every time I try to play a video it says "the specified stream type is not recognized," the colors appear strange, or I see the video just fine, but I don't hear anything. What should I do?

You might need the newest Windows codec (the compression algorithm for the media file). When you first attempted to install Windows Media Player, you may not have had the necessary permission to install software, or your Internet security may have been set to "Medium" or "High." This will prevent the codecs from being properly installed. Change your Internet security to "Low" during the installation process, or see your network administrator for proper installation.

  1. In Windows Media Player, I clicked on a video, and it asked if I wanted to download and install a new codec. What should I do? Or, I installed a new codec, and now I'm having problems watching or hearing the videos. What should I do?

If you try to view a video and your computer asks you if you want to install a new codec, first check your security settings before selecting "yes." In Internet Explorer, in either the View or the Tools menu, find the "Internet Options" dialog box and open it. Click on the "Security" tab in this window. Make sure that your security setting for the Internet Zone is set to "Low" before installing the new codecs.

If you select "yes" to add a new codec, you must restart your system for the new codec to function properly. If you installed a new codec, but did not follow these instructions, you may now be having problems. If you are having problems after installing a new codec, download the latest version of Windows Media Player and install it. Once installation is complete, restart your system. You should then be able to see and hear all the videos properly.

  1. The Windows Media Player screen appears green with pink wavy lines. What should I do?

To fix this Media Player problem, try to disable YUV flipping.

Note: You must open the Windows Media Player separately under Start, Programs, in order to access these options.

Open Windows Media Player.
Click "Tools" and chose "Options."
Choose the "Performance" tab.
Click the "Advanced" button.
Remove the check from next to "Use YUV flipping."
Click "OK" twice.
Close the player and try the webcast again.

  1. On my Macintosh, when I click on the link to perform the webcast test, I do not see a video with sound or audio; instead, I see an ORC webcast banner with what looks like a Lego block with question marks on it. What should I do?

You need to install the flip4Mac Plugin for Apple Quick Time. You can download it from the Microsoft Download Center.

  1. During the live webcast the movie stopped. What should I do?

If you are on a Windows machine, right-click within the browser window and select refresh.

If you are on a Macintosh machine, make sure the browser window with the webcast is your active window, then use the keyboard shortcut "CMD-R" to reload your page.

  1. How do I set the Windows Media Player to work behind a proxy or firewall? (not for people with modems or other kinds of direct connections to the Internet.)

Some schools and offices have firewalls or proxy servers which are between your computer and the Internet. If this is your case, you need to make sure that your Windows Media player is set up to pass through the firewall.

Note: You must open the Windows Media Player separately under Start, Programs, in order to access these options.

In the Windows Media Player:

Click on "Tools." Then click "Options."
Click the "Network" tab.
Highlight HTTP. Then click the "Configure" button.
You have four options to choose from. The default option is "Use proxy settings of the Web browser."
Click on "Use the following proxy server:" and enter the name (or IP address) of your proxy. You may need to speak with your IT department for this setting.

You will also want to contact your IT department to make sure that the firewall and/or proxy server for your building or school is allowing network traffic through port 80 for both http://128.146.97.29 and http://www.ohiorc.org

  1. Whenever I try to view a video, it tries to connect to the server, and then it says "closed." What should I do?

To find out more information on what the error is, right-click in the viewing window of your Windows Media Player after it says "closed" and select "Error Details" from the menu. This should give you more information on what the problem is so you can find the correct help topic here.


Top

  1. I received a "connection to the server failed," "could not connect to the server," or similar error message. What should I do?

Chances are we are experiencing heavy web traffic which is tying up our streaming server. Try watching the video again later, and it should be fine.


Top

  1. I have a T1 or cable connection, but whenever I try to watch a video, it's choppy or the frame rate is much slower than the audio rate. What should I do?

If you have tried increasing your buffer size and made sure you have the proper bandwidth selected, then most likely this is caused by you having either outdated hardware (a Pentium or lower), an outdated operating system (Win 3.1), an outdated browser (Netscape 3, IE 3), or not enough memory, video RAM, etc.

The Windows Media codecs are optimized for Pentium III or higher and run fine on Pentium II, but on a Pentium or lower, they choke completely. Also you need a fair amount of system resources, RAM, VRAM, etc., to get good results.


Top

  1. I received a "your security settings do not allow the new decompressor to be installed" error message. What should I do?

This is caused by Windows Media Player trying to automatically install a newer version of the codec needed to play the video. Before you click to watch the video, set your browser's security in the Preferences (or Internet Options) to "Low." Then click to watch the video, and you should not get this error. After you have watched the video, you can set your browser security back to "Medium" or "High" and watch all the videos you want since Windows Media Player will have properly installed the newer version of the codec.

  1. Even though I have all the system requirements, why can't I see or hear any videos?

There are a few possibilities:

If you launch the videos on Windows while other audio applications -- including but not limited to mp3 players -- are running, you may have trouble hearing sound. If this is the case, close your browser and all audio applications. Restart your browser and re-enter our website.

From the Start menu, go to the Control Panel and select "Network and Internet Connections". Then select "Windows Firewalls" for firewall configuration settings if you are connecting to the streaming videos from work and are behind a firewall. Should you have difficulties, you may want to consult with your network administrator for guidance.
