We have update our streaming media pages for both the Webcasts and the Radio Factor Show so that they will work much better with a Macintosh. You can use either Windows Media Player or Real Player on the Macintosh and the player will show on the page, just like people on Windows PC's see. This has been tested with both Safari and Firefox browsers on Macintosh OS 10.3 and 10.4. Please let us know if you have any other suggestions for the Macintosh.
