That's strange. I have a 19" Acer LCD and I don't see any compresion, or artifacts on the screen. It just seems to run as if I was watching the DVD on my TV with DVD player. :/

If you are watching movie DVD's they will look fine, because movies are not interlaced.
It's the DVDs of TV shows, when played back on anything other than a 480i TV set, where the Apple DVD player fails big-time. Constant combing, far worse than any DVD playback system on the market.
If you haven't perceived it, don't ever let me or anybody else point it out to you, or it will forever drive you up the wall. Ignorance is bliss.
