1: You can go to this site:
dvdxml.com
sign up then download xml files into the appropriate movie directorys.
2: Or goto this site and download this software:
DVD Library Manager
DVD Library Manager allows you to edit the DVD information (meta data) used by DVD Library in Vista Media Center (VMC). It can download additional movie information from Amazon.com and IMDB.com.
I think option 2 is the better option to use.
I found when using the 2nd option, my DVD information would show instantly after a restarting of the computer. Wheras the first option needs to renew the info from the net.
