Windows XP Home Edition to Ant Movie Catalog to ? (1 Viewer)

[Surfer]

I want to put my DVD Movie Collection on External Hard Drive and use my computer (like I do for music with iTunes) to catalog my movies.
Then using the computer as a Media Center, locate the movie I want to watch, double click it and have the movie play on my TV.

I cannot get or find "Windows Media Center" for my system: (Windows XP Home Edition 2002 "Service Pack2").
1. Any Suggestions?

SO I am starting with: "Ant Movie Catalog "
2. What else do I need ?
3. I heard I need "MyFilms". Is that true?
4. If it is, Where do I get the latest Version?

Then MyFilms goes to or through "MediaPortal" which is like "Windows Media Center"
5. Is this correct?

6. Is there anything else I need to know?

7. Or, is there a better way to do this?

Thank You All
