This article describes three trouble shooting ideas to get the Mathcasts to play.
1. Firefox: Copy the link from the error page. Paste it in the browser. Check to see if it plays.
2. Still not working? Download the latest version of Quicktime. In Firefox:
- Go to Tools --> Add-ons.
- Under Plugins, get Quicktime Plug-In 7.7.4 (or the latest version).
- Activate.
- Repeat step 1 if necessary.
3. If step 1 and 2 above did not work, open the link in iTunes. Open iTunes:
- Go to File -->Open Stream.
- Paste the URL in the Open Stream window.
- Play the mathcast!
