Bluetooth and Wifi Don't Mesh?

[HostileJava]

I just got a set of Motorola S9 bluetooth headphones and they work just fine, as long as I'm not trying to listen to anything over wifi. Is this a known issue and is there a fix for it? I'm running the WM6 ROM and I have several pairings set up with my device but when I was trying to do this the only thing I had paired to it was the headphones. If I turn on wifi and try to stream an MP3 across my local network or a video using either Media Player or TCPMP it comes through all choppy. I also tried to stream using XM and ORB and the same thing happened. If I switch over to using EVDO I can stream XM and listen through ORB/Media Player with no problems.
