Due to the ability to customize individual encoding format and bandwidths, a system with the minimal requirements may not be able to view all presentations. The Presentation creator must determine at the time of creation the level of compatibility desired. With the proper configuration, RichCasts can be viewed on systems running Windows XP or later.

The following hardware and software are required to use Windows Media Player 9 Series for Mac OS X: Operating System
If the video stream becomes choppy or stalls, and or the slides stall or show a white space with a small red “X”, try pressing CTRL-R which will refresh the stream, and should resolve the issue. If this does not work, try closing the viewer and re-launching the webcast URL.
If you cannot see the video but hear audio and see slides, you may have low bandwidth. This generally occurs with Dial-Up users. The Windows Media player will control this automatically. As more bandwidth becomes available, so will the video.
If you have slides but no audio/video, your IT department, ISP, Hotel etc is most likely blocking port 1755 or one of the streaming video ports. You may need to call your ISP or in-house IT staff and address this accordingly.
If you cannot hear the presentation, please check your volume controls. There are 3 areas you may find volume controls: Inside the presentation window, just below the video area, is the Media Player volume control. If you find that you cannot adjust the volume, try clicking the speaker icon twice to mute, and then un-mute the volume. The + and - volume controls should now be available.
Go to Control Panel >> Sounds & Audio Devices. Adjust the volume slider and confirm that Mute is not selected. Speakers >> Your speakers may have a physical volume control dial or knob that you can use to increase or decrease the volume level.
