   Yes, but XMMS shows the fluctuations with VBR files.  If you didn't know   
   that, well, maybe you should use it.  A typical 128 Kbit-VBR fluctuates from   
   somewhere around 100 - 130 kbits/sec.   
      
   You also gotta think about the fact that Ogg Vorbis' compression algorithm   
   is slightly more superior.  For two identical songs, ripped from the same   
   track, and using a fixed rate 128Kbps encoder, I see on the average, a 10%   
   savings.   
      
   You can use, if nothing else, ogg123 to check the status of an ogg file,   
   whether it's VBR or fixed, and lots of other things.   
      
   Personally, I don't like to encode VBR files, it's easier and less CPU use   
   to not hafta find out what the next frame is encoded at and then decode it,   
   then switch again, frame, after frame, or block, after block, whichever it   
   uses, it slips my mind.   
      
   The idea is that the compression isn't in the fact that you've reduced the   
   bits per second - while that *IS* part of it - the rest is pure, actual,   
   compression.  If you don't know what compression is, you should check out   
   what JPEG, ZIP, RAR, gzip, bzip2... etc... those are all compressors, some   
   lossy, some lossless, but regardless, they are compressed formats.   
      
   You need to do some reading, yourself.   
      
   There's a reason Ogg Vorbis is better liked by some people, and for me, it's   
   the fact that my entire collection of songs and clips is roughly 10% smaller   
   then previously, meaning I can fit more music on it without buying another   
   drive.  That's more CDs that I can get, save, and put away in storage.  Yay.
