Assuming your screen is level then it's a matter of your PJ not being perpendicular to the screen. This can be caused by many things like the ceiling slightly sloping, pitch and yawl being off.
Getting the PJ true to the screen is all up to the adjustably of your PJ mount.
Give me more info how the distortion looks and I'll give you my best guess to fix it. Draw a picture if you must.
Also note that if you are basing your setup on a DVD that is 1.85:1 you will have slight masking bars on the top and bottom of your screen. This is because 16X9 screen are 1.78:1 aspect ratio. This always throws off first time users. You would have thought HDTV would have gone with 1.85:1 to lessen the confusion.
