I've had this problem before.

The cause?

Applie Quicktime.

It's getting just as bad as Real Media. Too bad I have to have QT installed because of my Digital Camera. You should be able to go in and tell it to remove all of its associations. If that's not the cause, than I dunno.

(Oh I'm running XP, I'm not sure if you are as well or not)
