I had exactly the same problem with My Music folder in XP Home Edition. It seemed that the crash was caused by the arrangement of icons in the folder. If the icons are arranged by artist or album, explorer will crash every time you open the media folder. In order to change this, right-click on the folder and select search. Don't write anything in the provided spaces, just click search. You will get a list of all the files contained within the folder. Now, right click anywhere on the page and select the 'arrange icons by name' option. Close the search window and open the media folder by double-clicking on it.
I hope this helps,
Seto.
