Well the a2dp stuff seems to be fairly cpu intensive, presumably because it's having to performing sbc encoding before sending the audio to the device (most devices support direct streaming of mp3 data but I don't think this is possible with mplayer, it is with gstreamer though). You should still be able to get reasonable mp3 playback, you won't get acceptable ogg playback though, as the combination of a2dp and ogg decoding appears to be too much for the cpu to handle. If you're getting very choppy playback with mp3s and you're using bluez4 then try running "hciconfig hci0 lm master; hciconfig hci0 lp hold,sniff,park" after starting the bluetooth daemon.
