Yeah, I can't much blame you for being squeamish about opening up a $200 investment and saying, 'I'm gonna void the warranty and stick my soldering iron on that motherboard..'

I've actually had more fun modding the xbox and making it do what it isn't supposed to do, than I have playing xbox games.

But yes, the .wma doesn't appear to be proprietary, as I played them on my windows 98 machine easily. I do wonder if you could rip lower bitrate wmas and copy them to the box and have them play properly. The only problem is that the songs title info is stored in a separate database file not the wma file itself (like mp3s with id3 tags), so I don't know how the box would handle ripped wmas. : ^ \
Hope I don't confuse you too much, I know I was confused not that long ago, I've been there d00d.
