It works fine on mine. It might be because I enabled DVD gallery in the registry though.
1) Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Media Center\Settings\DvdSettings
2) Under the 'ShowGallery' string change the value from 'Play' to 'Gallery'.
3) Restart MCE and you will not see My DVD showing.
Then when in the DVD gallery I clicked info and added more DVD locations.
