I recently started ripping CDs to my new Classic 120GB iPod thru iTunes 8 using the Apple Lossless file format. Have never used it before. When you rip a CD to iTunes using the Apple Lossless file format, why does it use a variable bit rate? Shouldn't lossless files be a fixed bit rate? If I chose 320 kbps, iTunes rips all the songs at 320, not at a variable rate. You can see the results in the following screen shot.
