Some Projector Test DVDs

[camds78]

Hi All,

I'm looking at adding a Projector to my HT setup and I'm starting to audition a few models. Currently I'm looking at :-
Sony VPL-HS51 (http://www.projectorcentral.com/Sony-VPL-HS51.htm)
Panasonic PT-AE700 (http://www.projectorcentral.com/Panasonic_Home-PT-AE700U.htm)
Hitachi PJTX100 (http://www.projectorcentral.com/Hitachi-PJTX100_UltraVision.htm)

I'm not asking for which one is the best because I know everyone has there own opinion on which one is the best.

I'm looking for some good opinions on the best Test DVDs to show up the strengths and weaknesses of the image from each one.
