Also bought 40CV700 this last Nov2011, still very happy and contented after reading feedbacks and reviewing its features.
I agree, of previous comments, i do not need the USB to play my media file. Got the Xtreamer
as I only watch in full surround audio.
Suggest you guys try to look for DVD available for fine tuning...result is Big difference!
Got me the HIVI audio/video DVD and was very helpful..
Audiowise: Achieved centering, surround, imaging.
Videowise: i have settings for dark room, and daylight..Color/temp/Black/White can be fine tuned.
After fine tune, i never used the presets.
