Upgrade to Media Player 9 for OS/X.
There is currently a "bug" in Windows Media Player for OSX that forces Windows Media Player to default to the lowest bitrate stream (i.e., 56k) irrespective of your connection bandwidth. This issue will likely be fixed in the next Windows Media Update.
If you would like to view a higher bitrate version contact
