I spent some time trying to get seeking working in WMA, the problem is  
the format is such a pain that it makes it very difficult to do.  The  
WMA header contains data that changes based on the amount of audio  
data, so the header has to be rewritten on the fly every time you  
seek.  I'm sure it's possible, just not as easy as the other formats.
