There is absolutely NO NEED for 'my movies' plugin here. This is a feature that exists in MCE:

1. Rip the DVD to your HDD in a place where you have your DivX.
2. With DVDShrink, remove extras, unneeded soundtracks. Leave all subtitles, they consume almost no space.
3. Open Media Center, go to my movies and browse until you get the folder where you ripped your DVD
4. Click on it, you're done! he DVD starts up!

That's a no-brainer!
