I've used Movie Collector for quite a while and it works as expected. It's not much of a looker and is definitely not as polished as MediaMan, but it has some extra features that I wish MediaMan possessed.

One of those wish list features that I wish MediaMan would implement would be an option to create a "Sort by" title. That way, movies like X-Men would be displayed before X2: X-Men United, since I could alter the Sort By title to override the default alphabetical order.
