People look - it's in the title!
It's for setting up HOME THEATERS.

Does your panasonic in the middle of the family room even spend 10% of it's time displaying movies? Most likely it's used for watching the evening news, sitcoms, and the kid's cartoons. This type of viewing is done in a wide variety of ambient lighting conditions, all of which affect the appearance of the display.
It is true that to a person unaccustomed to viewing a calibrated TV, a calibrated display will seem dark, especially under normal ambient lighting conditions.
HOWEVER, in a movie-plex, have you ever watched a movie with the overhead lights on? NO! In this situation, the picture on the silver screen would seem equally dark.
For those using this disc, it is meant to calibrate HOME THEATERS, period. That means the lights are off. JUST LIKE AT THE REAL THEATER.

any good reciever can test all the same things for you >>
not true, the reciever can calibrate it's own output levels, but cannot account for any inaccuracies/shifts in volume level between your DVD player source and the receiver.

This is a hot deal for home theater enthusiasts, and will annoy all but the people wanting to reproduce the theater environment in their home. Consider that statement seriously before purchasing.
Personally, I use the normal settings on my TV for normal viewing, and adjust the settings to the properly calibrated ones for DVD watching.
I hope this information helps you purchasing decision!
