I have a 23" HD Cinema Display, and everything looks crisp and beautiful...but when I play DVDs there are weird "line things" whenever there's movement on the screen (especially apparent in full screen mode).

I have OSX Panther and DVD Player 4.0...Please tell me there's something I can do to fix this!!

Thanks.

Take a close look at any regular television.

It is called "interlace" and some DVDs have it encoded into the picture. Depends on the DVD.

I know what you mean, but the picture honestly looks better on my old 1992 Sanyo television. There has to be a problem with my Mac DVD Player...I'd say its the monitor, but like I said, every other application (including things like video on FCP) look perfectly fine.

That's because your old Sanyo is an interlaced display, so interlaced video looks fine on it. Interlaced video on a progressive display, like a computer monitor, looks horrible. Unfortunately, Apple has not implemented deinterlacing techniques into DVD Player (for almost all computers). Try using VLC to play those DVDs which contain interlaced video. Generally, you'll only see interlaced video on DVDs that originated as television programs.

Incorrect.

All DVDs contain interlaced video.

Please read the above thread link I posted, it has some good discussion.
