don't know the exact reason but the weird scaling / filtering they used resulted in wrong sizing, off colors and such compared to intended. On the same TV, letting the HDTV upscale a DVD played back on a PS2 for example, the end result was often better and more faithful as intended.

I think we have the reason above. The PS2 does 480p but I don't believe it does 576p. (Certainly someone here will help fix that if it's wrong.) Certain HD sets don't like 576p and their upscalers do strange things. My understanding is it has to do with the need to multiply by 1.5 or 1.25, for a 720p set (example).

The 360 DVD player is just fine. If 576p didn't work 480p always does for HD sets. The DVD was worse at launch but has had many codec updates. The problem wasn't hardware.

I hope we don't have to cover again how the 360 only reads DVD flags and responds accordingly. Test DVDs aren't flagged, studio movies are flagged. Thus, the 360 looks worse on the quality test DVDs than it truly is.
