WMA transcoding problem

I have subsonic installed on my windows home server and have successfully got it working streaming my music through my firewall at work. I love it. mp3's work fine, however, wma files sound like loud radio fuzz...I'm assuming there is a transcoding problem with wma's. I have the standard audio transcoding pack with the command line settings set to the default as shown on the subsonic page.
Anyone else having problems transcoding wma's?
