I'm definitely not up on this guys, but someone had posted this link previously:
http://www.hometheaterinfo.com/dvdlist.htm
which is a very up-to-date listing of dvd's in several formats. He brought it to the axim in excel and opened it (after about 5 minutes)... not a pretty experience.
I tried to do the same thing in ListPro, but it would not handle a file that large.
In general I keep track of listings like dvds in listpro myself...
