Common Troubleshooting FAQ

No Video

• Java starts, but I don't see slides or the video -- You are probably using Netscape Navigator. We are actively working on fixing the infrastructure to support Netscape. For now, change to Internet Explorer or use the japanese server. Please send email to jgast@cs.wisc.edu if you still cannot see the lecture.
• The slides are too big -- right click and zoom out. If that makes the slides hard to read, grab the border between the video and the slide and drag it to make the slide window bigger.

Javascript errors

• Javascript errors -- Please report all javascript errors to jgast@cs.wisc.edu. The program is a work in progress.

No Sound

• On machines in CS&ST building -- even if your computer has a sound card, most CS machines do not have speakers. Use headphones.
• No error message, but no sound -- probably means IE didn't wait long enough when grabbing the sound. Double click on the speaker icon in your task bar (it runs SNDVOL32.EXE), click on mute all and then unclick it. The message causes IE to try again.
• Microsoft Windows Media Player complains that you do not have the right CODEC -- if you are not administrator on an NT computer, you do not have permission to install a CODEC (COmpression / DECompression) to decompress the audio. We chose VOXware to get the broadest compatibility.
• CSL removes your CODEC everytime you reboot -- send E-Mail to jgast@cs.wisc.edu to tell me which CODECs are installed in "ControlPanel / Multimedia / Devices / Audio Compression CODECs". In particular, look for the VOXware CODEC, look at its priority, and make it higher priority that whatever is stealing audio that it can't decode. We picked the VOXware CODEC because of its quality and because it ships in all installations of Windows Media Player (and both core and full).
