There IS such a thing as "the vlc codec pack," and I also installed it. I also have the process traymenu.exe in my startup folder. Apparently, it starts vlc media player in the task bar. According to
http://download.cnet.com/VLC-Codec-Pack ... 62970.html, this is one of the processes that comes with the vlc codec pack. Since I did not want VLC media player running in the task bar, I just deleted traymenu.exe from the startup folder in the start menu.
