Thanks Straycat!

I went ahead with the setup instructions in that post and it does work now for mplayer, but not the built-in media streamer or vagalume (which are two things I really wanted to utilize). I considered installing Canola2 so I could use mplayer through that and use the lastfm plugin instead of vagalume and the upnp plugin instead of media streamer, but it sounds like the lastfm plugin is not as good as vagalume and might not even work any more. I think I will take yukop4's advice and get a 3.5mm bluetooth dongle (not a modem ). Thanks again for the help, and everyone else too!
