My Sony has a problem when viewing NTSC DVD's, the top inch of the screen "pulls". The outher corners have quite a lot of distortion which causes objects to bend as the camera pans up/down. It's not a geometry problem, and is fine with PAL sources. The shop says they have heard of this before with Sony TV's but I don't believe them, there's never been anything on this forum about this. Anyone else have the same problem? My TV is the DX40, they have offered to swap it for a Panasonic or another DX40 but nothing else comes close, I want digital and 50hz.
