Whenever I go to front row on my Macbook, I can't play music or videos unless I open iTunes prior to pressing the menu button on my apple remote.
If I don't open iTunes, then it hangs when I click Music or Movies in front row. One time, I let it go to see if it would load them eventually, and it took so long that my Macbook went to sleep. After a while I will have to Cmd-Alt-Esc to get out of Front Row, and then I get a message saying "iTunes has unexpectedly quit". This only started after installing the latest version of iTunes.
