I have owned and own many DVD players, Toshiba,Panasonic,Denon,Pioneer,Awia, and others priced from $34 to several $1000. None have had the Video Quality of the $200 Oppo, at least to my eyes.
Of course most of the others did not have DVI output. IMHO, if you have HDMI or DVI inputs on your video display, you can do no better that the Oppo. At $200 it is a throw-away when the HD-DVD/Blu Ray mess is sorted out.
