If you've got a wife, you'd better have a Harmony, or some other universal remote, that'll do the switching. The idea that men are from Mars and women from Venus is never more true than with a home theatre. The only thing my wife wants to know is which single button to press for TV, DVD, VCR, CD, and how to adjust the volume. Try to get a woman to do anything more is asking for WW3.
Of course, that's just my opinion; I could be wrong...
