I ran a spyware scan right before lunch, which I do regularly, and the WMP was knocked out during the scan. I've noticed that the same happens to the Realplayer stream, so it was no big deal. Since I was leaving for lunch, I just shut it down and restarted when I returned.
Realplayer frequently rebuffers during the day, even with no change in my computer operations. Sometimes it will kick out completely, and I have to hit the 'play' button again. Periodically (once every two weeks or so) it will kick out and hitting 'play' will give me the "Please come back during broadcast hours" message. If that happens, I have to log back into the website and restart the Real stream from there.
I don't use WMP too often, usually only when Realplayer can't find the stream, but when I do it seems to operate much better than the Real stream. It's quite frustrating.
