It seems like a bug in the way media player is requesting the stream, or the way hijack is sending it. I'm sure Mark doesn't test with Media Player. I've always used winamp, but I just fired up WMP8 to test this out. Everything seems to work fine for me.

Just thinking out loud... Could it be a problem with file associations? Maybe install winamp, test that out, then reinstall WMP and see if the problem goes away.
