If you're using a Mac and you want to download a sermon, hold down the CTRL button and click on the link. When the menu appears, select "Save Link As..."
Once the file has downloaded (this may take several minutes) you can then open the saved MP3 file in Windows Media Player.
Simply click on Start->Programs->Accessories->Entertainment->Windows Media Player and then choose File->Open and browse to the saved file.
The links labelled 'low' are the low quality version and those labelled 'high' are the high quality version.
The low quality version takes less time to download.
