With your caution about your wife's lack of interest in the "supernatural", I am still going to recommend "Dark City", one of the most original sci-fi films of the past 10 years. It is not only a wonderfully unique movie, but also has a soundtrack that will really wring out your HT system.
Here are a few other favorites of "demo" quality:
1. "Super Speedway" -- originally an IMAX film about the development of the 1999 Newman-Haas Indy car, it has some great footage and excellent sound (but will probably not have much appeal to your wife...).
2. "Stop Making Sense", the DVD of the 1985 concert by the Talking Heads. Arguably the best rock concert on DVD.
3. "Calle 54", a superb music DVD featuring a number of the best contemporary Afro-Cuban and Latin jazz stars. The soundtrack was the 2001 Grammy Award winner for Best Latin Jazz recording.
4. "Saving Private Ryan" -- at least the first 30 minutes is demo quality.
